FERROMAGNETIC-RESONANCE IN AMORPHOUS (FE1-XCOX)(62.5)SI12.5B25 ALLOYS

Amorphous (Fe1-xCox)(62.5)Si12.5B25 (x = 0.0, 0.1, 0.3, 0.4, 0.6, 0.8, 1.0) alloy ribbons are studied with ferromagnetic resonance (FMR) at room temperature. The FMR experiment data of the samples x = 0.0, 0.1, 0.3, 0.4, 0.6 are used to calculate saturation magnetization M(s), gyromagnetic ratio gamma, Lande g-factor, and constant of effective uniaxial anisotropy K.
