Domain wall motion in ferromagnetic nanowires driven by a localized Gaussian thermal gradient
M. A. Jafar Pikul, M. A. S. Akanda, M. T. Islam
We investigate magnetic domain wall (DW) dynamics in a uniaxial ferromagnetic nanowire under the localized Gaussian temperature profile of a laser spot using the stochastic Landau-…

Field-free ultrafast magnetization reversal of a nanodevice by a chirped current pulse via spin-orbit torque
Y. D. Liu, M. T. Islam, T. Min +2
We investigated the magnetization reversal of a perpendicularly magnetized nanodevice using a chirped current pulse (CCP) via spin-orbit torques (SOT). Our findings demonstrate tha…

Thermal effect on microwave pulse driven magnetization switching of Stoner particle
S. Chowdhury, M. A. S. Akanda, M. A. J. Pikul +2
Recently it has been demonstrated that the cosine chirp microwave pulse (CCMP) is capable of achieving fast and energy-efficient magnetization-reversal of a nanoparticle with zero-…
