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…

Reduction of Tc due to Impurities in Cuprate Superconductors
Kiwamu Kudo, Kosaku Yamada
In order to explain how impurities affect the unconventional superconductivity, we study non-magnetic impurity effect on the transition temperature using on-site U Hubbard model wi…
