AbstractThe relative flux creep rate S(t)≡d lnM/d ln t of a single crystal of Ba 1-xK xBiO 3-δ(BKBO) was measured up to a few degrees Kelvin below the irreversibility line. It is nearly constant at low temperatures but rises sharply after a threshold temperature T t. Above T t, the creep changes from logarithmic to non-logarithmic decay. All these are very similar to those observed in Y 1Ba 2Cu 3O 7-δ (YBCO) samples and suggest a flux-lattice phase sub-boundary. The ratio between the boundary field B t and the irreversibility field B i falls between 0.15 and 0.25 for both BKBO and YBCO at various temperatures, implying a possible close relationship between the boundary and the irreversibility line. © 1992.
