Abstract
Magnetic field dependence of equilibrium magnetization M(H) was calcul ated for type II superconductors (kappa = 100) of a size comparable to the London penetration depth. The interactions between the Abrikosov vortices and the surface were taken into account as well as the real g rain size distribution In fine-grained polycrystalline HTSC. A good qu antitative agreement between the calculated dependencies and the exper imental quasireversible magnetization curves (7 = 85 K) was obtained.
