摘要：

A magnetization step due to isolated Co2+ spins in Cd1-xCoxS was observed at 30 mK. The magnetic field at this step gave 2D=1.32±0.04 cm-1 for the single-ion axial anisotropy constant of Co2+. This value is close to those obtained by other methods. EPR experiments at 96 GHz gave 2D=1.28±0.04 cm-1. The EPR data suggest the existence of a Koster-Statz term in the spin Hamiltonian. © 1994 The American Physical Society.
