摘要：
The magnetotransport and magnetostatic properties of synthesized dilute magnetic semiconductors (DMS) InxMn1-xSb were studied. The samples with x = 0.75 - 1.33 at% Mn manifested the hysteresis at room temperature with the coercive force below 50 Oe and the saturation field about 5 kOe. Both the magnetoresistance and Hall effect were positive. With the Mn concentration decrease the magnetoresistance significantly increased. The co-doping of these DMS with Zn enhances the ferromagnetic properties according to the kinematic exchange theory. (c) 2006 Elsevier B.V. All rights reserved.
