Magnetomechanical Ratios for Fe-Co Alloys

Abstract

Magnetomechanical ratios for four Fe-Co alloys were measured by the Einstein-de Haas method. Previous measurements of Fe, Co, Ni, and Fe-Ni and Co-Ni alloys are reviewed, thus completing magnetomechanical determinations for the binary alloys of these three ferromagnetic elements. Magnetomechanical ratios for these binary alloys are all different from those calculated from the effective atomic magnetic moments and angular momenta measured in experiments on the unalloyed constituents.
