    摘要: Transport and magnetization of MgIn2-xMnxO4 polycrystalline pellets (0 < x < 0.55) have been measured from 2 to 300 K. Doping MgIn2O4 with Mn results in an increase in electrical resistivity and a decrease in electron concentration. The electrical resistivity increases with decreasing temperature throughout the temperature range and variable-range hopping is observed at low temperatures. The diamagnetic pure MgIn2O4 changes to paramagnetic after doping. The paramagnetism of the doped samples obeys the Curie-Weiss law. The magnetic-field dependence of the magnetization of the doped samples can be well described by the Brillouin function. © 2007 Elsevier B.V. All rights reserved.
