| Popis: | InCrP:Zn was prepared using the implantation with Cr concentrations of 0.3% and 0.7%, respectively. It was confirmed that the photoluminescence peaks near 0.85(D, Cr) eV and 0.96(e,Cr) eV were Cr-correlated PL bands by the implantation of Cr. Especially, each 0.85(D, Cr) eV and 0.96(e,Cr) eV peaks were separately observed based on InP. In triple-axis x-ray diffraction patterns, the samples revealed a shoulder peak indicative of intrinsic InCrP. Ferromagnetic hysteresis loops measured at 10 K and 300 K were observed and the temperature-dependent magnetization showed ferromagnetic behavior ≥300 K, which reveals obvious and enhanced ferromagnetic spin coupling mediated by hole. |
