Abstract(in English) | 3 kinds of characterization method of Co-based perpendicular media using Q-band (~34 GHz) Ferromagnetic resonance (FMR) were introduced: 1) Quantitative evaluation of H_k and g-factor for Co-based alloy films: dynamic magnetic properties simultaneously derived for CoPtCr film using resonance fields of FMR. g-factor increases from 2.11 to 2.19 when Co content decreases from 85 to 65 at.%. 2) Evaluation of magnitude of the interlayer exchange in the stacked media (media consists of continuous film layer/ interlayer/ granular layer): magnitude of interlayer exchange coupling J_ |
