摘要：

Pressure effects on the structural parameters are investigated in a half-doped manganites (Nd0.125Sm0.875)(1/2)Sr1/2MnO3, by means of the synchrotron-radiation x-ray powder diffraction measurement. The compound shows a pressure-induced metal-insulator transition due to the subtle competition between the double-exchange interaction and the charge-ordering instability [Y. Tokura et al., Phys. Rev. Lett. 76, 3184 (1996)]. We have found that application of pressure induces the four-long and two-short deformation of the MnO6 octahedra. We present a possible scenario for the pressure-induced charge-ordering.
