Askerzade, I. N.Tanatar, Bilal2016-02-082016-02-0820070921-4534http://hdl.handle.net/11693/23412Generalization of two-band Ginzburg-Landau (GL) theory to the case of anisotropic mass is presented. The temperature dependence of the anisotropy parameter of upper critical field γc 2 (T) = Hc 2∥ (T) / Hc 2⊥ (T) and angular dependence of Hc2(θ, T) are calculated using anisotropic mass two-band Ginzburg-Landau theory of superconductors. It is shown that, with decreasing temperature anisotropy parameter γc2(T) is increased. Results of our calculations are in agreement with experimental data for single crystal MgB2. © 2007.EnglishAngular dependenceMass anisotropyTwo-band superconductivityUpper critical fieldAnisotropySingle crystalsSuperconductivityAngular dependenceGinzburg-Landau (GL) theoryMass anisotropyUpper critical fieldSuperconducting materialsArticle10.1016/j.physc.2007.04.218
