Detailed magnetization curves show a first-order phase transition in single-crystal ErRh/sub 4/B/sub 4/ at H/sub c2/ for the temperature range 3.3 K greater than or equal to T greater than or equal to 1.4 K when the field is along the anti a axis. Below 3.3 K, the discontinuity in magnetization at H/sub c2 grows with decreasing temperature and moves to lower fields, eventually developing into the spontaneous moment in the ferromagnetic state. In the anti c direction the superconducting magnetization curves exhibit ordinary type-II behavior. 4 figures.
