Magnetic properties of ultra-thin 3d transition metal alloys I: spin and orbital moments and confirmation of Slater-Pauling theory



Martin A. Schoen, Juriaan Lucassen, Hans T. Nembach, Thomas J. Silva, Bert Koopmans, Christian Back, Justin M. Shaw


The structure and static magnetic properties - saturation magnetization, perpendicular anisotropy, Landé 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 (XRD), superconducting-quantum-interference-device (SQUID) and vector-network-analyzer ferromagnetic resonance (VNA-FMR) measurements. Furthermore the interfacial contributions to the perpendicular magnetic anisotropy are investigated in a thickness series of select alloy concentrations. The results match single published data points and theoretical prediction, providing a comprehensive compilation of thin film NixCo1-x, NixFe1-x and CoxFe1-x alloy magnetic properties.
