Layer-selective detection of magnetization directions from two layers of antiferromagnetically-coupled magnetizations by ferromagnetic resonance using a spin-torque oscillator
Taro Kanao, Hirofumi Suto, Koichi Mizushima +1
We use micromagnetic simulation to demonstrate layer-selective detection of magnetization directions from magnetic dots having two recording layers by using a spin-torque oscillato…
Reservoir Computing on Spin-Torque Oscillator Array
Taro Kanao, Hirofumi Suto, Koichi Mizushima +3
We numerically study reservoir computing on a spin-torque oscillator (STO) array, describing the magnetization dynamics of the STO array by a nonlinear oscillator model. The STOs e…
Measurement of nonlinear frequency shift coefficient in spin-torque oscillators based on MgO tunnel junctions
Kiwamu Kudo, Tazumi Nagasawa, Rie Sato +1
The nonlinear frequency shift coefficient, which represents the strength of the transformation of amplitude fluctuations into phase fluctuations of an oscillator, is measured for M…
Amplitude-Phase Coupling in a Spin-Torque Nano-Oscillator
Kiwamu Kudo, Tazumi Nagasawa, Rie Sato +1
The spin-torque nano-oscillator in the presence of thermal fluctuation is described by the normal form of the Hopf bifurcation with an additive white noise. By the application of t…
Synchronized Magnetization Oscillations in F/N/F Nanopillars
Kiwamu Kudo, Rie Sato, Koichi Mizushima
Current-induced magnetization dynamics in a trilayer structure composed of two ferromagnetic free layers and a nonmagnetic spacer is examined. Both free layers are treated as a mon…
