Effect of short-time magnetic relaxation on hysteresis curves in single-crystal Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x}.
We have studied the role of short relaxation time on magnetic hysteresis in a Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub x} single crystal. Effects were examined by comparing isothermal magnetization curves obtained over a range of temperatures as a function of the applied magnetic field, H, for magnetic field ramp rates of 3 and 30 Oe/s. At low temperature, a second magnetization peak, H{sub p}, was produced by differences in magnetic relaxation occurring over a short period during the initial stage of relaxation. The data suggested an absence of pinning crossover for H {approx} H{sub p}.
