摘要：
The linear ac magnetic response of three Bi2Sr2CaCu2Ox single crystals with various doping states was investigated with a miniature two-coil mutual inductance technique in magnetic fields parallel to the c axis. The dissipation peak appeared right below T-c, and a drop in dissipation was observed at a frequency-independent temperature T-D together with an increase in shielding signal, upon field cooling the sample. The observed frequency-independent feature can be understood as a consequence of the thermally induced dimensional crossover.
