Mouhoub, Asma. "All-inductive observation of linear dynamics and nonlinear processes of spin waves in synthetic antiferromagnets". Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPAST147.
Testo completoSpin waves are the eigen-excitations of magnetic materials. They exhibit specific properties such as nonlinearity. This property makes them potentially suitable for applications in neuromorphic computing and magnonic logic devices. Synthetic antiferromagnets (SAFs), composed of two ferromagnetic layers separated by a non-magnetic layer that favors antiparallel magnetizations, are particularly effective for studying the nonlinearity of spin waves. A comprehensive understanding of the magnetic properties of SAFs is essential before exploring their nonlinear properties. The interlayer coupling is a degree of freedom that confers a large tunability to SAFs, which allows their customization in several spintronics applications. The efficient use of this magnetic configuration requires an in-depth understanding of the magnetic properties and their correlation with the material structure. We established a reliable procedure to quantify the interlayer exchange coupling and the intralayer exchange stiffness in SAF. We applied this procedure to the ultrasmooth and amorphous Co₄₀Fe₄₀B₂₀ (tmag)/Ru (0.7 nm)/CoFeB (tmag) structure. The complex interplay between the two exchange interactions results in a gradient of the magnetization orientation across the thickness of the stack, which alters the hysteresis and the spin wave eigenmodes of the stack in a nontrivial way. We measured the frequency-field dependence of the first four spin waves confined within the thickness of the stack. We modeled these frequencies and the corresponding thickness profiles of these spin waves using micromagnetic simulations. The comparison with the experimental results allows us to deduce the magnetic parameters that best account for the sample behavior. The exchange stiffness is Aex = 16 ± 2 pJ/m, independent of the film thickness. The interlayer exchange coupling starts from -1.7 mJ/m2 for the thinnest layers and it can be maintained above -1.3 mJ/m2 for CoFeB layers that are as thick as 40 nm. Frequency-field dependence allows the identification of conditions that exhibit nonlinear interactions. For specific configurations of the applied static magnetic field HDC the frequency of the acoustic magnon mode (fac) becomes half of the optical magnon mode frequency (fop), a favorable condition to investigate nonlinear phenomena in SAF. We developed an experimental setup based on propagating spin wave spectroscopy and we investigated the nonlinear processes inductively by varying the applied field HDC, the pumping frequency and the microwave power arriving at the simple. Two phenomena are observed: the doublets near fpump/2 evidence a three-magnon process where one optical magnon at fpump split into two acoustic magnons at fpump/2 - δ and fpump/2 + δ. 2). A strong halo around fpump could be a four-magnon scattering process, in which two optical magnons at fpump annihilate and create two new optical magnons. We focused on the three-magnon splitting process on a device patterned by optical lithography, featuring a 1.8 μm wide single-wire antenna. We showed that the population of the created magnons varies exponentially with the amplitude of the rf excitations above a certain threshold, which is 1.8 mT. Furthermore, to explore the dynamics of magnon creation, we apply rf pulses with various durations. We developed an analytical model that we compared to the experiment to effectively determine the growth rate of the population of the acoustic mode. To investigate spin waves in confined nanometric geometries, we fabricated new devices using electron beam lithography that feature 100 nm and 150 nm wide U-shaped antennas on top of magnetic conduits. This enables the excitation over a large range of wavevectors ∆k = 10 rad/μm corresponding to a frequency interval of ∆f = 4.13 GHz. In contrast to the 1.8 μm wide antenna, which excites a narrower range of wavevectors ∆k = 2 rad/μm corresponding to ∆f = 0.64 GHz

Testo completoFtsL, DivIB and DivIC are three membrane proteins involved in bacterial division. Their function remains uncertain, but is mutually dependant through the formation of complexes. To contribute to the structural knowledge of bacterial division proteins, and to bring insights on the function of the three cited proteins, we carried out a structural study on a model system of recombinant soluble proteins from S. Pneumoniae: FtsL, DivIC and DivIB. We have studied by several biophysical techniques (NMR, SANS, SAXS, BIA by SPR) the extracellular part of DivIB, a constrained complex of the extracellular parts of FtsL and DivIC, and the interaction between this complex and the extracellular part of DivIB. The extracellular part of DivIB is composed of three domains. The central domain of DivIB is structurally closed to its orthologue in E. Coli. DivIB interacts with a complex of the extracellular parts of FtsL and DivIC, via this central domain. We have identified an epitope of interaction on this domain. The C-terminus domain of FtsL and DivIC are essentials for the interaction with the extracellular part of DivIB. Indeed, a low-resolution model of the three proteins complex shows that the central domain of the extracellular part of DivIB is located at the tip of the complex of the extracellular parts of FtsL and DivIC. We have evaluated different models of the association of FtsL, DivIC and DivIB in the cell with these new structural data

Testo completoS. Pneumoniae causes more than one million deaths per year worlwide. Understanding cell division, a vital process for bacteria, is important in order to find innovative therapeutic molecules. DivIB/FtsQ, DivIC/FtsB and FtsL are central proteins of the divisome assembly to the septum. We have demonstrated that they form an essential ternary complex for pneumococcal division. Contrary to both ftsL and divIC, divIB is not essential for viability and growth of S. Pneumoniae in rich medium. However, the divIB null mutant does not grow in chemically defined medium. In the absence of DivIB and protein synthesis, the partner FtsL is rapidly degraded, whereas other division proteins are not affected, pointing to a role of DivIB in stabilizing FtsL. This is further supported by the finding that an additional copy of ftsL restores growth of the divIB null mutant in defined medium. Functional mapping of the three distinct a, ß and gamma-domains of the extracellular region of DivIB revealed that a complete ß domain is required to fully rescue the deletion mutant. Most importantly, the deletion of divIB increases the susceptibility to ß-lactams, more evidently in resistant strain, suggesting a function in cell wall synthesis. DivIB would be a good target to restore the efficiency of the most used antibiotics in the world, the ß-lactams

Testo completoThe increasing trend towards organizing the production of goods and services into networks as a result of the quest for flexibility in the face of fierce economic competition raises critical issues for industrial relations. Our thesis examines the precarization of jobs in the externalized segments of production networks. It is based on three case studies focusing on the networks of public and private homecare services in Quebec. Critical law studies have shown that labour law, based on the model of the integrated firm and the binary employment relationship, fails to identify as employers some organizations whose action nevertheless has a decisive impact on working conditions in these networks. Our thesis thus aimed to shed light on the empirical reality of the power relations prevailing throughout the networks and their effects, using an interdisciplinary analytical model that integrates the legal and sociological dimensions. Results indicate that the legal employer of workers – most of them women – employed by private service providers integrated into the networks is most often an employment agency, a social economy enterprise or the individual using the homecare services. This employer is rarely identified as being among the public organizations which, under the aegis of state, exercise predominant power over these networks. The gap between the legal regulation of labour and the empirical reality of intra-network power leads to a precarization of the social protection and working conditions of these women workers. Thus, the weak protection of their rights to collective representation and collective bargaining facilitates the imposition of “just-in-time permanent availability”, combining lean management logic with domestic work logic, and leads to a gendered and racialized deskilling of their jobs compared to the situation prevailing in the public sector. Our study nevertheless shows that some innovative practices involving reticular collective action – in particular practices implemented by local associations of disabled persons using the services and by a union of female agency workers – have had an influence on these power dynamics.
