We carried out an investigation of the effect of quasi-hydrostatic pressures up to 1.2 GPa in pure and Rh-doped RuSr2GdCu2O8 compounds, by means of measurements of electrical resistivity in magnetic fields up to 9 T. The onset temperatures for superconductivity, and for magnetic order in the undoped RuSr2GdCu2O8 compound are T-c approximate to 50 K, and T-m approximate to 133 K, respectively. The partial substitution of Rh for Ru lowers both these transitions temperatures. However, the effect of pressure for all compositions studied, up to 10% substitution, was to increase both T,, and Tm. The effect of pressure on the upper critical magnetic field of the pure, and Rh-doped compounds is discussed. (AU) | |
