Nonlinear cw NMR behavior, similar to that observed on ferromagnets at high rf powers, has been observed in superfluid /sup 3/He-B using a superconducting quantum interference device (SQUID) magnetometer in fields of 31, 102, 180, and 308 Oe and at a pressure of 21 bar. It is observed that beyond some threshold value of the transverse H/sub 1/ field the z component of magnetization anomalously decreases and is followed by a rapid increase back to the normal resonance curve as the frequency of the H/sub 1/ field is swept through resonance.
