TL;DR: In this paper, the Curie temperature of Mn-doped GaN films has been obtained by varying the growth and annealing conditions of the GaN and they have been shown to have ferromagnetic behavior with hysteresis curves showing a coercivity of 100−500 Oe.

Room temperature magnetic (Ga,Mn)N: a new material for spin electronic devices
M. L. Reed,M. K. Ritums,Hans H. Stadelmaier,M. J. Reed,C. A. Parker,Salah M. Bedair,Nadia A. El-Masry +6 more
TL;DR: A new dilute magnetic semiconductor (Ga,Mn)N grown by metal organic chemical vapor deposition (MOCVD) is reported in this paper, where the direction of the easy axis and the Curie temperature varies with the growth conditions, the latter ranging from 38°C to 75°C Secondary ion mass spectroscopy (SIMS) confirms diffusion of Mn into the GaN to a depth of 380 A
