Abstract (sommario):

This article focuses on spintronics with metallic nanowires. It begins with a review of the highlights of spintronics research, paying attention to the very important developments accomplished with tunnel junctions. It then considers the effect of current on magnetization before discussing spin diffusion and especially spin-dependent conductivities, spin-diffusion lengths, and spin accumulation. It also examines models for spin-polarized currents acting on magnetization, current-induced magnetization switching, and current-driven magnetic excitations. It concludes with an overview of resonant-current excitations, with emphasis on spin-valves and tunnel junctions as well as resonant excitation of spin-waves, domain walls and vortices. In addition, the article reflects on the future of spintronics, citing in particular the potential of the spin Hall effect as the method of generating spin accumulation, free of charge accumulation.

Abstract (sommario):

This chapter begins with Faraday’s law, which states that electromotive forces power everything by virtue of the charge e of an electron, and introduces spinmotive forces which reflect the magnetic moment of an electron. This motive force reflects the energy conservation requirements of the spin-torque transfer process that is at the heart of spintronics. The Stern-Gerlach experiment that used spin-dependent forces established the existence of spin. It is shown here that conservative forces would exist even if an electron was not charged, and do exist for uncharged excitations, such as magnons or phonons. Such forces are especially important in ferromagnetic materials where the spinmotive force commonly drives an electronic charge current due to the higher mobility of the majority electrons.

Abstract (sommario):

This textbook details the basic theory of ultrafast molecular spectroscopy starting from time-dependent quantum mechanical perturbation theory in Hilbert space. The emphasis is on the dynamics of nuclear and electronic motion initiated and monitored by femtosecond laser pulses that underlies nonlinear optical signal formation and interpretation. Topics include short-pulse optical absorption, the molecular adiabatic approximation, transient-absorption spectroscopy, vibrational adiabaticity during conformational change, femtosecond stimulated Raman spectroscopy, multi-dimensional electronic spectroscopy and wave-packet interferometry, and two-dimensional wave-packet interferometry of electronic excitation-transfer systems. Numerous exercises embedded in the text explore and expand upon the physical concepts encountered in this important research field.

Abstract (sommario):

In this chapter, some prospects in the field of electron and nuclear spin dynamics are outlined. Particular emphasis is put ona situation where the hyperfine interaction is so strong that it leads to a qualitative rearrangement of the energy spectrum resulting in the coherent excitation transfer between the electron and nucleus. The strong coupling between the spin of the charge carrier and of the nucleus is realized, for example in the case of deep impurity centers in semiconductors or in isotopically purified systems. We also discuss the effect of the nuclear spin polaron, that is ordered state, formation at low enough temperatures of nuclear spins, where the orientation of the carrier spin results in alignment of the spins of nucleus interacting with the electron or hole.

Abstract (sommario):

After a review of fundamental notions such as absorption, emission and the properties of excited states, the chapter introduces excited-state electron transfer. Several examples are given, using molecules to realize photodiodes, light emitting diodes, photovoltaic cells, and even harnessing photochemical energy for water photolysis. The specificities of ultrafast electron transfer are outlined. Energy transfer is then defined, starting from its theoretical description, and showing its involvement in photonic wires or molecular assemblies realizing an antenna effect for light harvesting. Photomagnetic effects; that is, the modification of magnetic properties after a photonic excitation, are then studied. The examples are taken from systems presenting a spin cross-over, with the LIESST effect, and from systems presenting metal–metal charge transfer, in particular in Prussian Blue analogues and their molecular version.

Abstract (sommario):

This article examines the THz emission from high-temperature superconducting (HTS) cuprates in the mesoscopic state using the intrinsic Josephson junction model. Cuprate superconductors are high-temperature superconductors that exhibit exotic electromagnetic properties. One of the remarkable features of HTS cuprates is high anisotropy due to their layered structures. Almost all HTS cuprates are composed of stacks of CuO2 layers and blocking layers which supply charge carriers to the CuO2 layers. The crystal structures of the HTS cuprates naturally form Josephson junctions known as intrinsic Josephson junctions (IJJs). This article first describes the basic theory of IJJ and the mechanism of THz emission before discussing the effect of temperature inhomogeneity on the emission properties. It then introduces a novel IJJ-based THz emitter that utilizes laser heating. Theoretical results show that the THz emission is caused by the strong excitation of transverse Josephson plasma waves in IJJs under a direct current bias.

Abstract (sommario):

Here, some prospects for future studies in the field of electron and nuclear spin dynamics are outlined. In contrast to previous chapters where the electron interaction with multitude of nuclei was discussed, in Chapter 8 particular emphasis is put on a situation where hyperfine interaction is so strong that it leads to a qualitative rear rangement of the energy spectrum resulting in coherent excitation transfer between electron and nucleus. The strong coupling between the spin of the charge carrier and of the nucleus is realized; e.g., in the case of deep impurity centers in semiconductors or in isotopically purified systems. We also discuss the effect of the nuclear spin polaron; that is, the ordered state, where the carrier spin orientation results in alignment of spins of the nucleus interacting with the electron or hole. Such problems have been briefly discussed in the literature but, in our opinion, call for in-depth investigation.

Abstract (sommario):

The book treats in a unified way electronic properties of molecules (magnetic, electrical, photophysical), culminating with the mastering of electrons, i.e. molecular electronics and spintronics and molecular machines. Chapter 1 recalls basic concepts. Chapter 2 describes the magnetic properties due to localized electrons. This includes phenomena such as spin cross-over, exchange interaction from dihydrogen to extended molecular magnetic systems, and magnetic anisotropy with single-molecule magnets. Chapter 3 is devoted to the electrical properties due to moving electrons. One considers first electron transfer in discrete molecular systems, in particular in mixed valence compounds. Then, extended molecular solids, in particular molecular conductors, are described by band theory. Special attention is paid to structural distortions (Peierls instability) and interelectronic repulsions in narrow-band systems. Chapter 4 treats photophysical properties, mainly electron transfer in the excited state and its applications to photodiodes, organic light emitting diodes, photovoltaic cells and water photolysis. Energy transfer is also treated. Photomagnetism (how a photonic excitation modifies magnetic properties) is introduced. Finally, Chapter 5 combines the previous knowledge for three advanced subjects: first molecular electronics in its hybrid form (molecules connected to electrodes acting as wires, diodes, memory elements, field-effect transistors) or in the quantum computation approach. Then, molecular spintronics, using, besides the charge, the spin of the electron. Finally the theme of molecular machines is presented, with the problem of the directionality control of their motion.
