We have successfully grown Mn-doped chalcopyrite ZnSnAs2 single crystals from the melt using the vertical-temperature-gradient Bridgman method. We have observed that Mn-doped ZnSnAs2 is ferromagnetic with a Curie temperature of 329 K. The coercive field is 18 Oe at 300 K. The calculated magnetic moment from the saturation magnetization was 3.63 mu(B) per Mn atom at 5 K. (C) 2002 Published by Elsevier Science Ltd. References: 16
