Abstract
The thin-shell formulation is applied to a combined finite element-boundary element technique to study the magnetic shielding efficiency of superconducting layers and hybrid superconducting-ferromagnetic sandwich structures in 3-D domains. The behavior of the superconducting material, assumed to be in a Meissner-like state, is here described by the London model. The numerical simulations are validated by comparison with the experimental results obtained for magnesium diboride samples having different shapes (i.e., disk, cup) and immersed in uniform low dc magnetic fields.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
