| Abstract: | We have studied the pressure dependence of the superconducting transition temperature of amorphous (Mo0.6Ru0.4)86B14 for hydrostatic pressures up to P ～ 9 kbar. The transition temperature Tc decreases with pressure at a rate dTc/dP=-(9±1) mK kbar-1. We estimate the Grüneisen parameter and the volume dependence of the electron-phonon coupling constant. |
