(Color online) Schematic diagram of SThM-FMR setup and stripe orientation.
(Color online) FMR spectrum of the Co stripe taken in the SThM-FMR setup with microwave amplitude modulation. Inset: in plane angle dependent conventional FMR showing the amplitude of the FMR field derivative as gray scale vs applied field angle ( axis) and external field ( axis). I–III mark the resonances further discussed by OOMMF and locally resolved SThM-FMR.
(Color online) FMR frequency spectrum calculated by OOMMF for external field perpendicular to the Co stripe with 85 and . Each spectrum shows three types of resonances: (I) rim mode, (II) backward volume modes, and (III) uniform mode. Dashed line corresponds to the cavity frequency of the SThM-FMR setup
(Color online) Topography and thermal amplitude image of SThM-FMR with external field perpendicular to the Co stripes at (upper images corresponding to mode III in Figs. 2 and 3) and topography thermal amplitude and phase images for rim resonance with external field perpendicular at (lower images corresponding to mode I in Figs. 2 and 3).
(Color online) Top: cross section of the magnetization distribution of the Co stripe for external field perpendicular to the stripe calculated by OOMMF. Bottom: thermal heat distribution across the Co stripe calculated from thermal diffusion equation for the heated areas taken from the upper image.
