Magnetic and transport properties of single-crystalline In1-xMnxSe (x=0.01 and 0.10) have been measured. In1-xMnxSe exhibits a prominent magnetization hysteresis between 90 and 290 K. In,-xMnxSe is conducting with increasing resistance at low temperatures and a small hysteresis between 90 and 290 K with the cooling trace having lower resistivity. The magnetization above and below the hysteresis is consistent with a paramagnetic signal. A Curie-Weiss fit to the data yields a value of J(eff)/k(B)=-240 K. The data are consistent with a saturated component contributing to the hysteresis and a paramagnetic phase that scales with concentration. (c) 2005 American Institute Of Physics.
