Nanomagnetism is the discipline dealing with magnetic phenomena specific to structures
having dimensions in the submicron range. This Colloquium addresses the challenges and …

Light elements having 2p electrons such as B, C, and N are common elements that have
played an important role in various functional materials. In particular, nitrides have long …

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 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 …

Spin momentum transfer in a nanomagnetic device with perpendicular magnetic anisotropy
for both free and fixed magnetic layers is studied. The perpendicular anisotropy is induced …

The currents in magnetic multilayers are spin polarized and can carry enough angular
momentum that they can cause magnetic reversal and induce stable precession of the …

We develop a model of the current-induced torque due to spin transfer in a layered system
consisting of two ferromagnetic layers separated by a nonmagnetic layer. The description is …

Negative anisotropic magnetoresistance (AMR) is observed in Fe 4 N film from 4.2 to 300 K.
The AMR ratio rises with temperature in a stepwise fashion near 50 K, and is accompanied …

Magnetic materials with negative spin polarization have attracted attention for their potential
to increase the design freedom of spintronic devices. This study investigated the effects of off …

We propose and demonstrate an experimental method to evaluate spin-transfer-torque
(STT) efficiency in current-perpendicular-to-plane giant magnetoresistance devices, which …
