非晶态超导体的转变温度和霍耳系数之间的经验关系

在大量的非过渡金属和合金中,非晶态的超导转变温度T_c与其霍耳系数R_H以及与相应的液态金属霍耳系数R_HL之间存在着一个经验关系,并由这个经验关系可以判断,到目前为止已报道过的无序金属Be,Tl,Zn,Pb和Hg还没有真正做到非晶态。 关键词：

AN EMPIRICAL CORRELATION BETWEEN SUPERCONDUCTING TRANSITION TEMPERATURES Tc AND THE HALL COEFFICIENTS IN AMORPHOUS SUPERCONDUCTORS

It is found that there is an empirical correlation between the superconducting transition temperatures T_c and the Hall coefficients R_H of amorphous states in numerous non-transition metals and alleys. The same correlation is also exist between the superconducting transition temperatures T_c of amorphous states and the Hall coefficients R_HL, of corresponding liquid metals. Prom these empirical correlations we judge that disordered metals, including bismuth thalium zinc, lead and mercury, which have been reported up to now, remain to be not really amorphous.
