Texto completoThe rapid growth in scale and complexity of neural network architectures in today's machine learning and artificial intelligence applications is creating a significant demand for advanced hardware solutions. The semiconductor industry is actively seeking next-generation storage technologies that can offer improved speed, density, power consumption, and scalability. One such technology that shows great promise for high-performance data storage and processing is magnetoresistive random access memory (MRAM), which stores information in the magnetic state of materials. However, with the continuous requirement of high-density and ultrafast scenarios, antiferromagnet as the basic unit of MRAM shows obvious advantages. Antiferromagnetic materials have negligible macroscopic magnetism, making them highly robust to external magnetic fields. This property also allows for the absence of dipole interactions between adjacent bits, enabling higher-density integration. Additionally, antiferromagnetic materials exhibit high-frequency dynamics up to the terahertz range, theoretically enabling faster write speeds than ferromagnetic devices. However, such fully compensated magnetic moments make the magnetization state of the antiferromagnetic material difficult to manipulate and detect by traditional electrical methods. In this thesis, we demonstrate the antiferromagnetic exchange bias switching in three-terminal magnetic tunnel junctions and achieve electrical detection of antiferromagnetism by the tunnelling magnetoresistance with a ratio over 80%, which is two orders larger than previous methods. This is achieved by imprinting the state of antiferromagnet IrMn on the CoFeB free layer. We further realize current polarity-dependent switching, rather than current orientation-dependent switching of IrMn down to 0.8 ns. We identify two switching mechanisms, the heating mode and the spin-orbit torque driven mode, depending on the current pulse width. The latter case is supported by numerical simulations, which suggest that spin-orbit torque generated by Pt induces the precession of IrMn and exchange coupling at the IrMn/CoFeB interface determines the switching polarity of IrMn. Furthermore, to break the ferromagnetic and electrical write speed limit and further explore the antiferromagnetic switching speed, we experimentally realize exchange bias switching by a single femtosecond laser pulse. In the IrMn/CoGd structure, the perpendicular exchange bias is investigated for different IrMn thicknesses and CoGd concentrations. Using the optimized structure, the exchange bias was switched under a single femtosecond laser, and the dependence of the exchange bias variations with different laser fluence and pulse numbers was detailed investigated. The pump-probe time-resolved measurement is used to demonstrate the exchange bias switching time scale of less than 100 ps. The grain structure of polycrystalline IrMn films and the amorphous state of CoGd alloy layers are accurately described using atomistic simulations. The IrMn exhibits a faster demagnetization than ferromagnetic materials and each IrMn grain remagnetizing to a single-domain state in only 2 ps. In addition, the different grains of IrMn exhibit independent and stochastic probabilistic switching in the ultrafast time scale. The electrical and all-optical manipulation of exchange bias system allows ultrafast, field-free and energy-efficient control of antiferromagnet with high ordering temperature and thermal stability, making it highly suited to applications

Exchange bias between a ferromagnet (FM) and antiferromagnet (AFM), which is utilized to pin the magnetization of a FM into a fixed direction in space, is essential in commonly used electronic components such as magnetic recording heads and magnetic memory cells, as well as novel magnetic logic and memory devices. However, the exchange bias effect has been optimized in materials and used in devices for decades without a good scientific understanding, both due to lack of nanoscale research and conflicted results from differences in fabrication and feature size. In this thesis, we present a special fabrication method that produces exchange bias reliably and consistently. We also show the results of both experimental and simulated investigation of the properties of exchange biased nanostructures such as domain formation, magnetostatic interactions, and response to field-driven switching. -A fabrication method for creating locally exchange biased nanostructures is first developed. By etching back a predeposited FM film, and regrowing a thin FM layer and then the AFM film, this hybrid method combines the benefits of a clean interface produced using subtractive methods and the scalability produced using additive methods. Its consistency is analyzed through vibrating sample magnetometry (VSM) and scanning electron microscopy (SEM). Next, the fabrication method is applied to an array of nanodots with varying ion beam etch durations and dot diameters, demonstrating a reduced exchange bias for small diameters, and no significant change in exchange bias unless the ion beam etch duration exceeded 30s. Based on the consistency of this method, new device-like patterns were fabricated both experimentally and by modeling, in which a grating of AFM stripes was exchange biased with a continuous FM film. Competing magnetic interactions were found in the modeling, and produced extraordinary hysteresis loop shapes in the experimental samples. Next, a grating of AFM stripes was exchange biased with a 900 offset grating of FM stripes using the same fabrication method, which simulates an array of individual magnetic devices. A different set of competing magnetic interactions was found, and the feature sizes of the FM and AFM components were demonstrated to tune these interactions and thus the switching behavior of such devices. Exchange bias of materials with perpendicular magnetic anisotropy (PMA) was attempted by exchange coupling a PMA FM material with an in-plane FM material, which in turn exchange couples with the AFM material. However, the magnitude of the exchange bias was found to be negligible when compared to the coercivity of the PMA material.

Texto completoAnisotropic magnetoresistance (AMR) corresponds to the change of R in an ferromagnetic material with the angle between electric current and magnetization. Sensors using this effect are suited to detect both angular and linear displacements. In this work, structural, magnetic and electric characterization were performed in order to study the exchange interaction between antiferromagnetic IrMn and ferromagnetic NiFe, in a bilayer and a multilayer. Simulations of the AMR measurements were performed and showed good agreement with the experimental data. Different anisotropy field values were observed. The difference between the anisotropy field and the exchange field values is responsible for the different AMR data sets extracted from each sample. The model takes into account the, anisotropy (uniaxial), Zeeman, and exchange-bias (unidirectional) energies was used to explain the observed behavior.
Magnetorresistência anisotrópica (AMR) consiste na variação da resistência de um material ferromagnético em função do ângulo entre a corrente elétrica e a magnetização do material, o que faz com que sensores que utilizam este efeito sejam promissores para medidas de posição tanto angulares quanto lineares. Neste trabalho, caracterização estrutural, magnética e elétrica foram realizadas para estudar a interação de troca entre camadas antiferromagnética de IrMn e ferromagnética de NiFe em uma bicamada e uma multicamada. Simulações das medidas de AMR foram realizadas e boa concordância entre os dados experimentais e os simulados foi obtida. Diferentes valores de campos de anisotropias foram observados. A diferença entre o campo de anisotropia unidirecional e o campo de exchange é responsável pela diferença entre as medidas de AMR obtidas. Um modelo que considera as energias de anisotropia (uniaxial), Zeeman e de exchangebias (unidirecional) foi usado para explicar o comportamento observado.
