Tq. Vu et al., DETERMINATION OF THE SINGLE-ION-ANISOTROPY IN CD1-XCOXS USING OPTICALFARADAY-ROTATION TECHNIQUE AT T=80 MK, Solid state communications, 94(3), 1995, pp. 197-200
The single-ion anisotropy constant D of Co2+ in Cd1-xCoxS was determin
ed from a magnetization step which was detected using optical Faraday
rotation technique. Experiments were performed in a dilution refrigera
tor at a temperature of approximately 80mK. Analysis of the data gave
D/k(B) = 0.96 +/- 0.02K.
