Spintronics is one of the emerging research fields in nanotechnology and has been growing
very rapidly. Studies of spintronics were started after the discovery of giant …

The spin Seebeck effect refers to the generation of a spin voltage caused by a temperature
gradient in a ferromagnet, which enables the thermal injection of spin currents from the …

The Rashba effect is an interaction between the spin and the momentum of electrons
induced by the spin-orbit coupling (SOC) in surface or interface states. Its potential for …

There is great interest in finding materials possessing quasiparticles with topological
properties. Such materials may have novel excitations that exist on their boundaries which …

Current-driven motion of the magnetic domain wall in ferromagnets is attracting intense
attention because of potential applications such as racetrack memory. There, the critical …

The energy bandgap of an insulator is large enough to prevent electron excitation and
electrical conduction. But in addition to charge, an electron also has spin, and the collective …

Thermoelectric generation is an essential function in future energy-saving technologies,.
However, it has so far been an exclusive feature of electric conductors, a situation which …

We propose a longitudinal spin-Seebeck effect (SSE), in which a magnon-induced spin
current is injected parallel to a temperature gradient from a ferromagnet into an attached …

The generation of electric voltage by placing a conductor in a temperature gradient is called
the Seebeck effect,. Its efficiency is represented by the Seebeck coefficient, S, which is …

This tutorial article introduces the physics of spin transfer torques in magnetic devices. Our
intention is that it be accessible to beginning graduate students. We provide an elementary …
