| Abstract: | The electrical resistivity of LaAg has been measured from 1–300 K at hydrostatic pressures to 12.4 kbar and the superconducting transition temperature Tc determined inductively to 23 kbar. For P ? 6.2 kbar a lattice transformation is observed at a temperature TM which increases rapidly with pressure. Tc shows an oscillatory pressure dependence, increasing initially from Tc (0) = 1.062 K. There is no obvious correlation between the pressure dependence of TM and Tc. |
