Investigation of the Einstein-de Haas Effect for Cobalt and for the Co-Ni Alloys

Abstract

Magnetomechanical measurements on cobalt gave a $g^{\prime }$ value of 1.838±0.003. This value for cobalt appears to be unaffected by changing from the hexagonal to the cubic phase, and is nearly the same as the value for nickel. Magnetomechnical measurements were also made on seven different alloys of the Co-Ni series. All of these alloys have $g^{\prime }$ values greater than that which characterize the constituent metals.
