Abstract
A detailed analysis of the magnetic response of field-cooled type-I superconducting hollow cylinders shows that the so - called “paramagnetic Meissner effect” can take place in opportunely devised multiply connected superconductors. Adopting simple circuital analogs of the latter superconducting systems, the magnetic susceptibility of micro-cylinders with one or two holes is studied by means of energy considerations.
