| 中文摘要 | We have synthesized Nd0.5Sr0.5MnO3 polycrystalline bulk samples by solid state reaction, which show ferromagnetic (FM), A-type antiferromagnetic (AF) and charge ordering charge exchange (CE)-type AF transitions on cooling from room temperature to 78 K. We consider that the abundant magnetic structures are caused by phase segregation. We have investigated and conjectured the orbital ordering behavior under hydrostatic pressures up to 7.5 GPa and found that low pressure favors the A-type AF phase with d(x(2)-y(2)) orbital ordering and the CE-type AF phase with d(3x(2)-r(2))/d(3y(2)-r(2)) orbital ordering, while suppressing the FM phase with disordered orbital ordering; however, high pressure favors the A-type phase and suppresses the CE-type AF phase. Transport property enhancement and large resistance changes under high pressures are observed. (C) 2005 American Institute of Physics. |
