摘要：

Magnetization measurements of the wurtzite highly resistive bulk crystals of GaN:Mn, codoped with Mg, are presented. Strong anisotropy of magnetization at low temperatures (2-10 K) was observed. The data were analyzed assuming Mn ions in d(4) configuration. The crystal field model taking into account cubic field of tetrahedral symmetry, trigonal field along the c-axis simulating hexagonal structure, tetragonal static Jahn-Teller distortion, and the spin-orbit interaction provides good description of the experimental magnetization data.
