Determination of the antiferromagnetic exchange constants between nearest-neighbour Mn 2+ ions in Cd 1- xMn xS and Zn 1- xMn xSe
Abstract
Steplike magnetization vs magnetic field dependence obtained in pulsed magnetic field up to 34 T in 1.8 K enables us to determine the value of the antiferromagnetic exchange constant between nearest-neighbour Mn 2+ ion ( J1). The analysis of the first and the second step position in the framework of a generalized cluster model [1] yields J1 = -8.6±0.9 K for Cd 0.945Mn 0.055 S and J1 = -9.9±0.9 K for Zn 0.95 Mn 0.05 Se.
