Abstract
We compare the local magnetization at a spatial singularity of superconducting U_(0.97)Th_(0.03)Be_(13) for different magnetic field histories. We find a reduction in the zero-field-cooled vortex flow relative to the field-cooled case, marked by a sharp onset coincident in temperature with the second (lower-temperature) transition in the specific heat. This effect is peculiar to the flux threading the hole of the torus, to (U,Th)Be_(13) samples with multiple superconducting transitions, and to the lower superconducting state with broken time-reversal invariance.
