中文摘要	The effect of hydrostatic pressure (P) and external magnetic field on the c-axis resistivity (rho(c)) and in-plane ac susceptibility (chi(ab)) of La1.2Sr1.8(Mn1-yRuy)(2)O-7 (y=0 and 0.075) single crystals have been investigated. The ferromagnetic transition temperature (T-C) increases, while the conductivity decreases, with Ru doping. The application of pressure strongly decreases rho(c) and shifts T-C to higher temperature for both the samples. For the undoped (y=0) sample, T-C increases almost linearly with P up to 2 GPa, while T-C for the Ru-doped sample starts to saturate above 1.0 GPa. In the ferromagnetic state, the nature of P dependence of chi(ab) of Ru-doped sample changes dramatically around 1.5 GPa. These results are explained by the pressure-induced spin reorientation from the basal plane to along the c-axis. (C) 2009 American Institute of Physics. [doi:10.1063/1.3256158]
