The effects of hydrostatic pressure to 21 kbar on the superconducting (T/sub c/) and magnetic (T/sub m/) critical temperatures are reported for thirteen body-centered tetragonal isomorphous compounds in the systems RERu/sub 4/B/sub 4/ and RE(Rh/sub 0/ /sub 85/Ru/sub 0/ /sub 15/)/sub 4/B/sub 4/ (RE=Pr,Nd,Gd,Tb,Dy,Ho,Er,Tm,Lu). Comparison of the two superconducting Lu compounds reveals a marked distinction between the volume dependence of T/sub c/ due to external pressure and the effect caused by alloying on the transition metal site which also affects unit cell volume. A contrasting behavior under pressure is observed for the magnetic and superconducting states for the three pairs of compounds comprised of RE=Dy,Ho,Er.
