Crystal-Field Splitting and Kondo Effect in Zn-Mn

Abstract
Magnetic-anisotropy measurements show evidence for the existence of crystal-field splitting of the transition-metal ion in zinc-manganese single crystals. Assuming the manganese ion has a spin value of 2, the maximum energy splitting Δ is 0.3°K. On the condition that ΔT, TKT<1, the Kondo behavior as indicated by the experimentally measured magnetic susceptibility is not seriously affected.
