Abstract

Manganese gallium nitride (Mn4-xGaxN) single crystals as well as Mn-doped GaN single crystals were prepared by heating a Mn-Ga-Na melt at 750°C and 5 MPa of N2 pressure. The Mn 4-xGaxN crystals had the cubic anti-perovskite-type structure (space group: Pm3m) with a lattice parameter a = 3.8886(9) Å. The single crystals exhibited magnetic transitions from a ferrimagnetic phase with a spin-glass-like disorder to an antiferromagnetic phase at 107 K, and then to a paramagnetic phase at 270 K. From these magnetic transition temperatures, the composition of the Mn4-xGaxN single crystals was estimated to be Mn3.07Ga0.93N.
