Abstract

The structure and static magnetic properties—saturation magnetization, perpendicular anisotropy, spectroscopic g factor, and orbital magnetization—of thin-film 3d transition metal alloys are determined over the full range of alloy compositions via x-ray diffraction, magnetometry, and ferromagnetic resonance measurements. We determine the interfacial perpendicular magnetic anisotropy by use of samples sets with varying thickness for specific alloy concentrations. The results agree with prior published data and theoretical predictions. They provide a comprehensive compilation of the magnetic properties of thin-film NixCo1x, NixFe1x, and CoxFe1x alloys that goes well beyond the often-cited Slater-Pauling dependence of magnetic moment on alloy concentration.
