The rapid development of information technology has led to urgent requirements for high
efficiency and ultralow power consumption. In the past few decades, neuromorphic …

Digital data, generated by corporate and individual users, is growing day by day due to a
vast range of digital applications. Magnetic hard disk drives (HDDs) currently fulfill the …

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 …

This book emerged from a close collaboration of the authors which started in the fall of 2000.
Early that year one of us (JS) had joined the Stanford faculty after spending nearly 15 years …

In order to explain recent experiments reporting a motion of magnetic domain walls (DW) in
nanowires carrying a current, we propose a modification of the spin transfer torque term in …

A self-contained theory of the domain wall dynamics in ferromagnets under finite electric
current is presented. The current has two effects: one is momentum transfer, which is …

In this paper, we review some of the key concepts in ultrathin film magnetism which underpin
nanomagnetism. We survey the results of recent experimental and theoretical studies of well …

The combined effect of spin-orbit coupling and exchange interaction in a single
ferromagnetic layer is investigated. It is shown that, in nonequilibrium regime, the spin-orbit …

This review describes in detail the essential techniques used in microscopic theories on
spintronics. We have investigated the domain wall dynamics induced by an electric current …

Direct observations of current-induced domain-wall propagation by spin-polarized scanning
electron microscopy are reported. Current pulses move head-to-head as well as tail-to-tail …
