X-ray ferromagnetic resonance spectroscopy[EPFL]

mt7344

We present a method to measure continuous-wave ferromagnetic resonance
FMR spectra based on
the core-level absorption of circularly polarized x rays. The technique is demonstrated by using a
monochromatic x-ray beam incident on an yttrium–iron–garnet sample excited by a microwave field
