Abstract

We compared three electrical detection techniques; differential resistance (dV/dI), RF/microwave transmission, and spin rectification measurements for magnetization dynamics in individual patterned sub-micron structures. Different electrical techniques allow us to identify distinctive magnetization dynamics; vortex excitation, domain wall (DW) motion, and ferromagnetic resonance (FMR) with different sensitivity. The spin rectification measurement has additional features, owing to its sensitivity to DW resonance and a non-linear magnetization response due to increasing RF power. Furthermore, the standard transmission technique with a bridge configuration confirms FMR signal by the spin rectification effect even with smaller magnetic response due to patterning of the element.
