采用二带Ginzburg-Landau(GL)理论模型,考虑到能带有效质量的各向异性,讨论了MgB_2超导体的相干长度ζ(T)、速率v_c(T)、伦敦穿透深度λ(T)和临界电流密度j(T)对温度T和角度θ的依赖关系.
Using the two-band Ginzburg-Landau (GL) theory model and considering anisotropy of the effective mass, we discuss the coherent length ζ(T) , critical velocity of Cooperpair v_c (T), London penetration depth λ(T), critical current density j(T) dependence on angular, temperature for MgB_2.
