摘要：

Specific-heat and thermal-expansion measurements on CeCu//2Si//2 samples of varying stoichiometry as well as on dilute (Ce, T)Cu//2Si//2 alloys (T:Y,La) indicate that the observed suppression of superconductivity in samples with 'high' unit-cell volume is associated with a reduction of the Kondo temperature and the occurrence of another cooperative phenomenon, probably magnetic in origin.
