Abstract：The penetration depth λ(T),coherent length ξ(T),high critical field H_(c2)(T)andcoefficients k_1(T)and k_2(T)of the type II superconductors at low temperature werecalculated by the generalized G-L equations.An expression of the structure of avortex line at low temperature was derived.The lower critical field H_(c1)(T)was eval-uated by some simplified assumptions.The effect of the impurities on λ,ξ,k_1,k_2and H_(c1)was also discussed.After the calculation,it shows that the Werthamer'sand Wang's equations are no longer valid while the applied field H_0 approachesto H_(c2)(T)at low temperature. 收稿日期: 1985-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 戴问民 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I4/45 1 #12 2 #12 3 #12 4 Werthamer,N.R.,Phys.Rev.,123(1963) ,663． 5 王竹溪,未发表资料,1973． 6 Caroli,C.,Phys.Lett.,9(1964) ,307． 7 Maki,K.;Tsuzuki,T.,Phys.Rev.,139(1965) ,A868 McConville,T.;Serin,B.,Phys.Rev.,140(1965) ,A1169． No related articles found!
