Static hysteresis and dynamic losses were characterized at 77 K for 0.21 mm thick polycrystalline gadolinium sheet having a predominant basal plane orientation with respect to the sheet rolling plane. Dynamic losses were separable into noninteracting hysteresis and eddy current losses, the static hysteresis losses making the major contribution to total losses at all frequencies (20-240 Hz) and inductions (1-2.5 T) investigated. Losses per cycle at inductions of 1. 1.5, and 2.0 T were linearly dependent on frequency with the intercept(s) at

being correlated with measured static hysteresis losses per cycle.
