Abstract
InMnP:Zn samples implanted with Mn (10 at. %) were annealed at 350 °C for 60 s and at 450 °C for 30 s. Using transmittance electron microscopy, both single crystalline and polycrystalline structures containing MnP and In Mn3 sized ∼20 nm were observed depending on the annealing condition. These samples exhibited two different Curie temperatures: TC1 at 291 K and another well above 291 K. The high temperature-ferromagnetic behavior up to TC1 and above TC2 is believed to have originated from two magnetic MnP and In Mn3 phases, respectively.
