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 Ni x Co 1−x , Ni x Fe 1−x , and Co x Fe 1−x alloys that goes well beyond the often-cited Slater-Pauling dependence of magnetic moment on alloy concentration.

“…However, this explanation does not account for our measured dependence of H 0 on alloy concentration, since the perpendicular magnetic anisotropy, described in Ref. [32], effectively exhibits opposite behavior with alloy concentration. An explanation for this is proposed in Ref.…”

“…[32] and the factor of 2 accounts for the presence of two nominally identical interfaces of the alloys in the cap and seed layers. In Figs.…”

“…Further details of the deposition conditions, XRD, FMR measurement, and fitting of the complex susceptibility to the measured S 21 parameter are reported in Ref. [32].…”

“…The alloy phases are denoted by color code described in Ref. [32]. and the inhomogeneous linewidth broadening H 0 are then determined from a fit to the linewidth H vs frequency f plot [22], as shown in Fig.…”

“…To examine this relationship, we plot α int versus (g-2) 2 (determined in Ref. [32]) for all samples measured here in Fig. 5.…”
