英文摘要
We tried to improve the sample-preparation of Ce-based superconductors and some interesting superconductors with 4d-electrons and to substitute some impurities for the constituent atoms in non-centrosymmetric superconductors such as CePt3Si and CeCoSi3 in the crystal structure. After that, some kinds of measurements for superconducting properties and NMR on these materials were done. As a result, some serious problems concerning quality in Ce compounds have still remained. BCS mechanisms, however, were found to be dominant in other 4d-electron systems.
