Abstract
The effect of hydrostatic pressure (P) and external magnetic field on the c-axis resistivity (pc) and in-plane ac susceptibility (Xab) of La1.2Sr1.8(Mn1−yRuy)2O7 (y=0 and 0.075) (y=0 and 0.075) single crystals have been investigated. The ferromagnetic transition temperature (TC) increases, while the conductivity decreases, with Ru doping. The application of pressure strongly decreases pc and shifts TC to higher temperature for both the samples. For the undoped (y=0) sample, TC increases almost linearly with P up to 2 GPa, while TC for the Ru-doped sample starts to saturate above 1.0 GPa. In the ferromagnetic state, the nature of P dependence of Xab 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
