摘要：

Employing the time differential perturbed angular distribution method, we have measured local susceptibility and spin relaxation rate of Fe-54 nuclei implanted in III-V and II-VI semiconductors, CdTe, CdSe, and InSb. The magnetic response of Fe, identified to occupy the metal as well as the semi-metal atom sites, exhibit Curie-Weiss type susceptibility and Korringa like spin relaxation rate, revealing the existence of localized moments with small spin fluctuation temperature. The experimental results are supported by first principle electronic structure calculations performed within the frame work of density functional theory. (C) 2014 AIP Publishing LLC.
