The magnetic and superconducting transition temperatures and upper critical fields have been measured for Gd/sub x/Er/sub 1-x/Rh/sub 4/B/sub 4/ and Gd/sub x/Y/sub 1-x/Rh/sub 4/B/sub 4/. The pressure dependence of T/sub c/ for the Er system for x< or =0.05 is 0.5 x 10/sup -2/ K/kbar. Both systems exhibit reentrant behavior, that is a superconducting transition followed by a magnetic transition at a lower temperature that destroys the superconductivity. For the Er system, the initial additions of Gd actually raise the superconducting critical field followed by the expected decrease for greater additions.
