Abstract

A report on the discovery of room temperature ferromagnetic (FM) semiconductor in chalcopyrite with T_c = 312 K was presented. It was observed that the samples showed a transition to the antiferromagnetic (AFM) state at a temperature below 47 K. The magnetic properties on the samples were investigated using superconducting quantum interference device (SQUID) magnetometer. The Laue x-ray diffraction (XRD) studies on the single crystals and θ-2θ powder diffraction on the polycrystalline samples were performed.
