Three-temperature atomistic spin-lattice dynamics in LAMMPS: a moment-consistent, fluctuation-dissipation-correct extension and its validation on ultrafast demagnetization and all-optical switching of GdFeCo
Chun-Yeol You, Jiwan Kim, Dong-Hyun Kim
Atomistic spin dynamics (ASD) codes like VAMPIRE simulate femtosecond-laser-induced ultrafast demagnetization and all-optical switching (AOS) on a rigid lattice; the SPIN package o…
Quasi-static strain governing ultrafast spin dynamics
Y. Shin, M. Vomir, D. -H. Kim +3
The quasi-static strain (QSS) is the product generated by the lattice thermal expansion after ultrafast photo-excitation and the effects of thermal and QSS are inextricable. Nevert…
The dynamics of a domain wall in ferrimagnets driven by spin-transfer torque
Dong-Hyun Kim, Duck-Ho Kim, Kab-Jin Kim +4
The spin-transfer-torque-driven (STT-driven) dynamics of a domain wall in an easy-axis rare-earth transition-metal ferrimagnet is investigated theoretically and numerically in the…
Magnetic Domain Wall Motion due to AC Bias-Driven Resonances
Duck-Ho Kim, Dong-Hyun Kim, Dae-Yun Kim +4
Most of the existing researches on the dynamics of a domain wall (DW) have focused on the effect of DC biases, where the induced velocity is determined by the bias strength. Here w…
RC-circuit-like dynamic characteristic of the magnetic domain wall in ferromagnetic nanowires
Hong-Guang Piao, Dong-Hyun Kim, Je-Ho Shim +1
We have investigated dynamic behaviors of the magnetic domain wall under perpendicular magnetic field pulses in ferromagnetic nanowires using micromagnetic simulations. It has been…
Perpendicular magnetic anisotropy and magnetization process in CoFeB/Pd multilayer films
Duc-The Ngo, Duy-Truong Quach, Quang-Hung Tran +3
Perpendicular magnetic anisotropy (PMA) and dynamic magnetization reversal process in [CoFeB nm/Pd 1.0 nm] ( = 0.4, 0.6, 0.8, 1.0, and 1.2 nm; = 2 - 20) multilayer f…
