Abstract
We calculate the free energy and equilibrium magnetization in highly anisotropic layered superconductors with strong defects produced by irradiation. We account for the entropy associated with different configurations of pancakes inside and outside of strong defects. We show how magnetization measurements provide information on pinning energy and how they determine the magnetic fields and temperatures at which pancake vortices are trapped inside strong defects. We discuss also the behavior of magnetization which may signal about decoupling of pancakes inside columnar defects.
