An attempt has been made theoretically to observe the different anisotropic properties of optimally doped iron-pnictide superconductors in the presence of an applied magnetic field. For this analysis, the modified phenomenological Ginzburg-Landau (GL) theory applicable to two-band superconducting systems has been used and found to be successful. In doing so, the anisotropic ratio with respect to the penetration depth and the Sommerfeld coefficient have been calculated for the system. The results obtained have been found to be very close to the experimental findings reported earlier. This analysis manifests that the proposed model can successfully be used to explain the anisotropy of multiband superconductors.

Ba(Fe0.926Co0.074)2As2单晶不同向异性性能分析

已在理论上尝试观察在外加磁场存在下最佳掺杂的铁元素超导体的不同各向异性特性。对于该分析，已使用适用于双波段超导系统的改良现象学金茨堡-朗道 (GL) 理论并发现该理论是成功的。在此过程中，已经为系统计算了相对于穿透深度的各向异性比率和 Sommerfeld 系数。已经发现获得的结果与早先报道的实验结果非常接近。该分析表明，所提出的模型可以成功地用于解释多波段超导体的各向异性。
