Abstract
In p-type GaN implanted with 5 x 10(16) cm(-2) dose of Mn+ ions, magnetization data after annealing showed ferromagnetic behavior at 10 K. The ferromagnetic signal for the sample annealed at 800 degreesC was stronger than the one at 900 degreesC, because of the predominant reaction of Mn with N atoms at 900 degreesC and the increase of the electron concentration with increasing annealing temperature. This suggests that ferromagnetism in Mn-implanted p-type GaN can be enhanced by optimising annealing temperature (< 900 degreesC).
