Description
Using the results of Abrikosov vortex energy distribution in the vortex-laminar model of polycrystalline superconductor [L.V. Belevtsov, Low Temp. Phys. 31, 116 (2005)], the magnetic and transport properties were investigated theoretically. It is shown that these properties depend strongly on grain size, grain-coupling strength, anisotropy ratio and 'surface smoothness' of materials. The first flux entry field Hp, the lower critical field Hc1 and the Gibbs free energy as well as the field dependences of magnetization M( H ), pinning potential Up( H ) and critical current density Jc(H) near Hc1 are calculated. The vortex-vortex interaction energy is also determined
