We describe structural, magnetic, and transport properties of the Cd1-x-yMnxCryTe ferromagnetic semiconductor alloy. Bulk Cd1-x-yMnxCryTe crystals containing up to 10% of Cr (y = 0.10) were grown by the Bridgman method and were found to be strongly p type and ferromagnetic, with the highest Curie temperature of 362 K observed for y = 0.10. Magnetotransport measurements reveal the presence of the anomalous Hall effect up to and above room temperature, providing evidence that the observed ferromagnetism is characteristic of bulk Cd1-x-yMnxCryTe. Our experiment data suggest that Cr ions play a crucial role in establishing ferromagnetism in this quaternary alloy.
