This book presents the anisotropy and multiband effects in newly discovered unconventional superconductors: cuprate superconductors, borocarbides, magnezium-diboride and oxypnictides. The physical properties of these unconventional superconductors and the application of the two-band Ginzburg-Landau theory to these superconducting compounds are explained. Temperature dependencies of fundamental superconducting parameters are calculated using the GL theory taking into account multiband-and anisotropy effects. A comparision of theoretical results and experimental data is conducted. Additionally, the analytical solutionof the microscopical Eliashberg theory and of the BCS theory is developed fortwo-band and anisotropic superconductors. Fluctuation effects in newly discovered superconductors are also discussed. Presents new unconventional superconductors in detail. Contains a variety of theoretical calculations and explanations of experimental data. Explains the application of two-band Ginzburg-Landautheory for the calculation of different physical parameters in new superconductor. Delivers a detailed description of fluctuation effects in two-band superconductors. Displays an analytical solution of the Eliashberg equations for two-band and anisotropic superconductors. INDICE: Physical properties of unconventional superconductors. Ginzburg-Landau (GL) analysis of new superconductorts. System of anisotropic Eliashberg equations and influence of multiband effects. Fluctuation effects in newly discovered superconductors.
