| 摘 要： | 本文应用平均场近似讨论了对角无序对局域电子配对系统的上临界磁场的影响。得到对角无序显著改变了上临界磁场的温度特性。我们把计算得到的上临界磁场和重费密子系统CeCu2Si2和UPt3的反常的H(c2)作了比较,发现所研究系统的H(c2)可以具有与之类似的温度特性。

| Abstract: | The effect of diagonal disorder on the upper critical field of the local electron pair system is studied in the framework of the mean field approximation. It is obtained that this kind of disorder greatly changes the temperature behavior of H(c2). Comparing che upper critical field of this system with those of heavy fermion superconductors CeCu2Si2 and UPt3, we find that it could have the similar unusual temperature dependence. |
