Abstract:The temperature evolution of the crystal structure for Nd0.5Sr0.5MnO3has been investigated by powder XRD between 125 K and 725 K. The structure can be described with a monoclinic symmetry (space group P21/m) in the temperature range of 125-175 K, while with the increase in temperature between 175 K and 575 K the structure involves a higher orthorhombic symmetry (space group Imma). The rhombohedral structure with space group R-3c is observed at high temperature region of 575-725 K. The increase in the magnetization at low temperatures can be ascribed to the field-induced short-range magnetic order of the Nd3+ions. The dc and ac susceptibility data show some anomalies around the FM-PM transition region which can be attributed to the glass behavior and magnetic relaxation. © 2017, Editorial Department of Transactions of NUAA.
