使用自助熔剂融化法成功的制备了Bi2 Sr2 CaCu2 O8超导单晶 .在对所得单晶进行输运性质的研究时 ,我们发现一种反常的物理特征 :在超导涨落区观察到反常的电阻峰 ,从Bi2 Sr2 CaCu2 O8单晶的颗粒超导电性方面我们给出了合理的解释 .
Bi2Sr2CaCu2O8 superconducting single crystals were prepared successfully by self-fluxing melting method. When studying the transport properties of the obtained single crystals, we found an anomalous physical characteristic: abnormalities were observed in superconducting fluctuations Resistance peak, we give a reasonable explanation from the particle superconductivity of Bi2 Sr2 CaCu2 O8 single crystal.
