摘 要:We have measured the resistance of some Bi_(2)Sr_(2)CaCu_(2)O_(8) superconducting single crystals along ab plane and the c *** some of the single crystals,a resistivity anomaly near the superconducting transition temperature is observed in the ab *** giant resistance peak is independent of the small driving current(I≤40 mA),and the peak is suppressed and vanished gradually with the increasing applied magnetic field(100 G).We proposed that the resistance peak is a quasi-reentrant behavior due to the superconducting phase inhomogeneous distribution.
