L. Dobrosavljevicgrujic et al., FLUX-PENETRATION AND PINNING IN SUPERCONDUCTOR-FERROMAGNET SUPERLATTICES, Physica. C, Superconductivity, 235, 1994, pp. 2749-2750
Flux penetration in superconductor-ferromagnet superlattices is studie
d theoretically. The parallel lower critical field is calculated and t
he characteristic temperature and layer thickness dependence is discus
sed. It is found that strong flux pinning and high critical current de
nsities are obtained for superlattices with thin ferromagnetic and thi
ck high-temperature superconducting layers.
