| 摘 要： | 测量了Bi2Sr2CaCu2O8单晶的ab面和c轴方 向电阻，在其超导转变温度附近发现了反常的电阻峰出现.其随外磁场(>100Gs)和电流的增 加而逐渐消失.文章认为这个反常的电阻峰是由于单晶中超导相的不均匀分布而导致的准再 进入行为.

| Abstract: | We have measured the resistance of some Bi2Sr2CaCu2O8 superconducting single crystals along ab plane and the c axis. In some single crystals, a remarkable resistivity anomaly near the superconduct ing transition temperature is observed in the ab plane. The peak is suppressed a nd vanishes gradually with increasing applied magnetic field (>100Gs) or transpo rt current. We proposed that the resistance peak is a quasi-reentrant behavior d ue to the inhomogeneous distribution of the superconducting phase. |
