We compare the local magnetization at a spatial singularity of superconducting U{sub 0.97}Th{sub 0.03}Be{sub 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{sub 13} samples with multiple superconducting transitions, and to the lower superconducting state with broken time-reversal invariance.
