EXPERIMENTAL CONDUCTION ELECTRON SPIN-SPLITTING FACTORS IN MOLYBDENUM AND OSMIUM

Abstract

Conduction electron spin-splitting factors have been determined from spin-zeros in quantum oscillations in magnetostriction arising from orbits on the lenses in Mo, and from harmonic ratios of oscillations due to the zone 7 ellipsoids in Os. The Mo results are in qualitative disagreement with results of LMTO calculations; a possible explanation of the failure of the theory is proposed. The Os results are in good agreement with theoretical calculations of g factors and exchange-correlation enhancement.
