Abstract
The Eu-151-Mossbauer effect in various high-T(c) superconductors is st udied in order to investigate the electronic state and the lattice vib ration of lanthanide. Trivalent europium is not magnetically ordered i n all the high-T(c) superconductors studied. Relation between the isom er shift and the lattice parameter is obtained in the T'-phase (EuCe)2 CuO4-delta, from which it is concluded that the Eu-O distance increase s by the doping of Ce4+ with a smaller ionic radii than Eu3+. Correlat ion between the Debye temperature and the superconducting transition t emperature is also discussed.
