Implication

Experimental study demonstrates exact agreement with the Kittel-Van Vleck relation across iron, cobalt, and nickel alloys, indicating linear decreases in ferromagnetic mean spin moments.

Key Points

To measure the magnetomechanical ratio and spectroscopic splitting factor in iron, nickel, and their binary alloys to test theoretical relations between magnetic moment and angular momentum.
Measured the magnetomechanical ratio (g′) and spectroscopic factor (g) on identical samples of pure iron and nickel.
Measured g factors across binary alloys of Fe-Ni, Fe-Co, and Co-Ni to evaluate effective splitting factor theories.
Evaluated the validity of the Kittel-Van Vleck relation (1/g + 1/g′ = 1) and Tsuya-Wangsness formulations for effective magnetomechanical ratios.
Validated the exact form of the Kittel-Van Vleck relation, showing that 1/g + 1/g′ = 1 is well satisfied experimentally for iron and nickel.
Found that calculated effective splitting factor (geff) curves match experimental data points across Fe-Ni, Fe-Co, and Co-Ni alloys.
Demonstrated that the mean spin moment contribution for fcc or hexagonal ferromagnetics with an average electron number above 26.8 decreases linearly at a rate of −1.05 μB per electron.
