Confirmation by SQUID magnetometry of FMR measurements of magnetization of ultrathin Fe-B amorphous films

Direct measurements were made by means of SQUID magnetometry of the magnetization of ultrathin Fe50B50 and Fe70B30 amorphous films at room temperature. The film thicknesses used included most of those investigated in the authors’ recent ferromagnetic resonance (FMR) determinations of the surface ani...

Zusammenfassung:	Direct measurements were made by means of SQUID magnetometry of the magnetization of ultrathin Fe50B50 and Fe70B30 amorphous films at room temperature. The film thicknesses used included most of those investigated in the authors’ recent ferromagnetic resonance (FMR) determinations of the surface anisotropy Ks and the magnetization M of such films. The directly measured values of M confirm adequately the M values obtained by computer fitting of a theory to experimental FMR data. Thus, the present experiments offer substantial support for the reliability of the FMR method for measurements of Ks and M in ultrathin films.
