The magnetic field dependence of Meissner susceptibility of ceramics samples with different grain size was studied. It was found that the behaviour of susceptibility in sintered samples can be nonmonotonous. The model based on magnetic flux freezing when crossing the "irreversibility line" is propos
The Hamiltonian of a superconductor with 4-fermion attraction is modified by adding a long-range magnetic interaction V between conduction fermions and localized spin 1/2 magnetic impurities. V has the form of a reduced s-d interaction. Using an asymptotic form of the system's free energy f(H,b) and
