Accelerate micromagnetic simulations with GPU programming in MATLAB
CoRR, 2015 A finite-difference Micromagnetic simulation code written in MATLAB is presented with Graphics Processing Unit (GPU) acceleration. The high performance of Graphics Processing Unit (GPU) is demonstrated compared to a typical Central Processing Unit (CPU) based code. The speed-up of GPU to CPU is shown to be greater than 30 for problems with larger sizes

Nonuniform Micromagnetic States in Thin Circular Dots
, 2014 [[abstract]]Micromagnetic states are strongly related to sizes of nano-dots. The quasiuniform state becomes unstable and transforms to a new nonuniform state as the diameter of the permalloy circular dot exceeds some critical size.

Study of Magnetic Vortex Core by Micromagnetic Simulation [PDF]
, 2014 電気通信大学博士（工学）2013Recently, a memory cell using the direction of a magnetic vortex core in a magnetic disk was proposed. In the magnetic disk, the curling magnetization structure(magnetic vortex) appears to reduce the demagnetizing energy. In the center of
