Gyromagnetic Ratios of the Iron-Nickel Alloys

Abstract

Measurements by magnetomechanical experiments show that the gyromagnetic ratios for the alloys of the iron-nickel series undergo changes for low values of the induced magnetic intensity. This leads to a high-and a low-intensity value for $g^{\prime }$ for each metal. Two distinct curves of $g^{\prime }$ vs percent nickel are thus obtained. Nine different rods were used in which the content of nickel in iron varied from 0% Ni to 100% Ni.
