The magnetization of In1-xMnxSe is calculated and measured from 140 to 400 K in magnetic fields up to 7 T for two crystals with concentrations x=0.014 and 0.027. The Mn ions enter the InSe bulk crystal substitutionally at the In lattice site and are responsible for the observed magnetization of the sample. A singlet model of isolated Mn ions with a spin-orbit coupling parameter of 38 cm-1 fits the experimental data from two different concentration samples for temperatures ranging from 140 to 400 K in fields up to 7 T. This agreement between the experimental magnetization and the theoretical magnetization for In1-xMnxSe expands our theoretical understanding of the III-VI diluted magnetic semiconductor (DMS) by adding a Se-based system and complements previous agreement reported for only two other III-VI DMS (Ga1-xMnxS and In1-xMnxS).
