| 中文摘要 | The structural and magnetic properties of Nd0.5-xPrxSr0.5MnO3 (x = 0, 0.1,0.2,0.3,0.4 and 0.5) system have been investigated. With the substitution of Pr in Nd0.5Sr0.5MnO3, it shows a gradual structure transformation from the Imma orthorhombic symmetry to the tetragonal 14/mcm phase, and the crystallographic transition remains incomplete, even in Pr0.5Sr0.5MnO3. A large bifurcation between zero-field-cooled (ZFC) and field-cooled (FC) susceptibility has been observed below Curie temperature (T-C), which is characteristic of coexistence of ferromagnetism (FM) and antiferromagnetism (AFM) at low temperature region. The magnetization of Pr0.5Sr0.5MnO3 is larger than that of Nd0.5Sr0.5MnO3, while Nd0.5Sr0.5MnO3 with more CE-type AFM shows larger magnetization than Nd0.3Pr0.2Sr0.5MnO3, which mixed with CE-type (majority) and A-type (minority) AFM at low temperature, indicating that the magnetization of Nd0.5-xPrxSr0.5MnO3 system is affected by A-site disorder combined with orbital ordering of A-type AFM and CE-type AFM.
