Large single-grain bulk RE-Ba-Cu-O (RE: rare earth elements) superconductors can trap large fields exceeding several teslas and thus can function as very strong quasi-permanent magnets. At present the maximum trapped field is essentially limited by the mechanical strength of bulk superconductors. The stress produced by refrigeration sometimes causes cracking. A large electromagnetic force will also act on the superconductors, when they trap large magnetic fields, leading to the fatal failure. We have recently found that epoxy resin can penetrate into the bulk superconductors under controlled conditions. It has been confirmed that a dramatic improvement of durability and field trapping capability can be achieved with resin impregnation.
