Magnetic noise induced by dc current in a micron-size magnetic wire
Akinobu Yamaguchi, Keiichi Motoi, Hideki Miyajima
The magnetic noise spectra induced by direct-current (dc) current flowing through a micron-scale ferromagnetic wire have been investigated. We have observed the noise spectra with…
Electric spectroscopy of vortex states and dynamics in magnetic disks
Minori Goto, Hiroshi Hata, Akinobu Yamaguchi +4
Spin-polarized radio frequency (RF) currents and RF-Oersted fields resonantly excite a magnetic vortex core confined in a micron-scale soft magnetic disk. In this study, we measure…
Ratchet propagation of a magnetic domain wall in a single magnetic wire with quantum interference
Akinobu Yamaguchi, Tomoaki Kishimoto, Hideki Miyajima
Quantum interference incorporating spatially asymmetric potential profiles is realized experimentally to manipulate a magnetic domain wall (DW) into a single multilayered wire whos…
Quantized spin waves and perpendicular standing spin waves stimulated by current in a single-layered ferromagnetic wire
A. Yamaguchi, K. Motoi, H. Miyajima
The rectifying effect of radio-frequency (RF) current is highly sensitive in terms of the spatial spin distribution and dynamics. It emerged that an additional spin wave mode was s…
Broadband ferromagnetic resonance of Ni81Fe19 wires using a rectifying effect
A. Yamaguchi, K. Motoi, H. Miyajima +2
The broadband ferromagnetic resonance measurement using the rectifying effect of Ni81Fe19 wire has been investigated. One wire is deposited on the center strip line of the coplanar…
Direct current voltage induced by microwave signal in a ferromagnetic wire
A. Yamaguchi, K. Motoi, H. Miyajima +1
Experimental results of rectification of a constant wave radio frequency (RF) current flowing in a single-layered ferromagnetic wire are presented. We show that a detailed external…
