High Ms Fe16N2 thin film with Ag under layer on GaAs substrate
AIP Advances, 2016 (001) textured Fe16N2 thin film with Ag under layer is successfully grown on GaAs substrate using a facing target sputtering (FTS) system. After post annealing, chemically ordered Fe16N2 phase is formed and detected by X-ray diffraction (XRD).

A Comprehensive Study of Temperature and Its Effects in SOT-MRAM Devices
Micromachines, 2023 We employ a fully three-dimensional model coupling magnetization, charge, spin, and temperature dynamics to study temperature effects in spin-orbit torque (SOT) magnetoresistive random access memory (MRAM).

Exploring dynamical magnetism with time-dependent density-functional theory: from spin fluctuations to Gilbert damping [PDF]
, 2002 We use time-dependent spin-density-functional theory to study dynamical magnetic phenomena. First, we recall that the local-spin-density approximation (LSDA) fails to account correctly for magnetic fluctuations in the paramagnetic state of iron and other
