| Research Abstract |
The transport phenomena and spin-diode effect of a single layered ferromagnetic Fe_<19>Ni_<18> nano-wires and nano-disks in a radio-frequency (RF) frequency region are investigated. The microwave rectifying effect in single layered ferromagnetic wires is induced by the anisotropic magnetoresistance oscillation due to the magnetization dynamics in the wires. This rectifying effect provides sensitive detection for the magnetization dynamics in nano- or micron scale magnets.
