Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

Spintronics is one of the growing research areas which has the capability to overcome the
issues of static power dissipation and volatility suffered by the complementary metal-oxide …

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 …

The recent discovery that a spin-polarized electrical current can apply a large torque to a
ferromagnet, through direct transfer of spin angular momentum, offers the possibility of …

This paper formulates a general analytic approach to the theory of microwave generation in
magnetic nano-structures driven by spin-polarized current and reviews analytic results …

The existence of magnetic domains arises from the action of several interactions present in
magnetic materials, mainly exchange, anisotropy, and dipolar. This chapter deals with some …

Spintronics materials have recently been considered for radio-frequency devices such as
oscillators by exploiting the transfer of spin angular momentum between a spin-polarized …

We present experimental and numerical results of current-driven magnetization switching in
magnetic tunnel junctions. The experiments show that, for MgO-based magnetic tunnelling …

We propose a generalized stochastic Landau-Lifshitz equation and its corresponding Fokker-
Planck equation for the magnetization dynamics in the presence of spin-transfer torques …

A generalization of spin-transfer torques in ferromagnetic structures is proposed. For a
spatially nonuniform magnetization, the spin torque has a form nearly identical to that in …
