补充资料:各向异性第二临界磁场(anisotropicsecondcriticalmagneticfield)
各向异性第二临界磁场(anisotropicsecondcriticalmagneticfield)

在主轴坐标系中,设磁场平行于主轴Z,由各向异性GL方程给出的各向异性第二临界磁场为

Hc2∥(T)=`\frac{2|\alpha(T)|(m_1^\**m_2^\**)^{1/2}}{\mu_0\hbare^\**}`

$=sqrt{2K_1K_2}H_c(T)$

这里α(T)为GL自由能密度展式系数,mμ*和Kμ(μ=1,2,3)分别为库珀对有效质量和GL参量的μ分量,e*为库珀电子对电荷量,$hbar$是除以2π的普朗克常数,μ0是真空磁导率,Hc(T)为热力学临界磁场。对层状结构氧化物超导体,GL参量Ka≈Kb=Kab,并有

Hc2∥(T)=$sqrt2K_{ab}H_c(T)$

Hc2⊥(T)=$(2K_{ab}K_c)^{1/2}H_c(T)$

Hc2∥和Hc2⊥分别为磁场与主轴Z(或晶轴C)平行和垂直时的第二临界磁场,其物理性质含义参见“第二临界磁场”。
