Magnetoresistance of UBe₁₃ at high pressures

We have measured the temperature dependence of the electrical resistivity of UBe13 for magnetic fields up to 8 T and pressures to 95 kbar. Pressure increases the temperature range over which ρ{variant} = ρ{variant}0 + AT2, while the pressure and magnetic field dependences of ρ{variant}0 and A reflect changes in the quasiparticle interactions. © 1990.
