| Abstract | : | Electrical resistivity p and thermopower S of Y_<1-x>R_xCo_2 (R=Gd, Tb, Dy, Ho and Er) Laves phase systems were measured at temperatures from 1.5 K to 300 K in magnetic fields up to 15 T and under hydrostatic pressures up to 2 GPa. The universal linear relation between the pressure and magnetic field derivatives of the resistivity, dp/dP vs. dp/dB, was observed in the Y_<1-x>R_xCo_2 systems. Similar scaling behavior was found for the thermopower dependence on pressure and magnetic field. |
