Abstract(in English) | We have studied magnetic and optical properties of transition-metal (Cr, Mn) and rare-earth (Gd, Dy) doped GaN grown by radio frequency molecular beam epitaxy (RF-MBE). GaCrN showed the ferromagnetic characteristics at 7-400K. We observed the PL emission from GaCrN layers. GaGdN also showed the ferromagnetic characteristics at 7-400K. Sharp PL emission was observed for GaGdN due to the intra-atomic f-f-transitions. GaCrN-based ferromagnet /nonmagnet/ ferromagnet trilayer structures were grown, for the first time, by radio frequency molecular beam epitaxy, in which the magnetoresistive effect was confirmed. |
