In the model of hole superconductivity the strength of the pairing tnteraclton depends on the local career denslts. This g~vt~ rise to a dependence of the gap function & on the band energy q. Fluctuat ions in the local potential energy will result m dtfferenl values of& at the Fermi energy and hence
Magnetization studies of critical currents Jc(H.L,T) have been carded out on Pb/Ge multilayers with a square lattice of submicrometer holes. Sharp peaks in Jc(H\_I.) have been observed at integer H n and rational Hk/1 matching fields. The existence of multi-quanta vortices confined by the holes is c
In this paper we present the field dependence of the flux line pinning force of very thin (d=2-l5.5 IlIn) single crystals of the anisotropic low temperature superconductor 2H-NbSe2' where the field is nOrJnal to the superconducting Nb-layers. Below BcD ~0.8 B e2 the pinning force can well be describ
