Learning-Performance Evaluation of a Physical Reservoir Based on a Vortex Spin-Torque Oscillator with a Modified Free Layer
Kota Horizumi, Takahiro Chiba, Takashi Komine
In this study, we numerically evaluate the learning performance of a vortex spin-torque oscillator (VSTO) with a modified free layer, called a modified VSTO (m-VSTO), in which an a…

Effects of magnonic Kerr nonlinearity on magnon-polaritons with a soft-mode
Takahiro Chiba
We theoretically study the effects of magnonic Kerr nonlinearity on magnon-polaritons (MPs) with a soft-mode in easy-axis ferromagnets coupled to a microwave cavity. Using an effec…

Chaotic magnetization dynamics in magnetic Duffing oscillator
Ryo Tatsumi, Takahiro Chiba, Takashi Komine +1
We propose a magnetic analogy of the Duffing oscillator--magnetic Duffing oscillator--which is characterized by a double-well magnetic potential of a ferromagnet with a uniaxial ma…
