Description
We report on the intrinsic ferromagnetic properties of wurtzite Ga0.937Mn0.063N diluted magnetic semiconductor grown by plasma-assisted molecular beam epitaxy. The growth conditions were carefully optimized to obtain single phase (Ga,Mn)N samples. The high structural quality is confirmed by x-ray diffraction experiments. Ferromagnetism is unambiguously demonstrated by both macroscopic magnetization measurements and x-ray magnetic circular dichroism spectra recorded at the Mn K-edge. The Curie temperature is found ≅8 K with a spontaneous magnetic moment of 2.4 μB per Mn at 2 K
