摘要：

Magnitudes {ie1345-1} of Cu magnetic spins in La-systems were directly observed as a function of the Sr- and Ba-concentrations x by measuring 63/65Cu nuclear heat capacity. The results show Cu magnetic spins in the superconductors of the both systems. In the La-Ba system, {ie1345-2} becomes large just at the concentration where the x dependence of the superconducting transition temperature Tc shows a drop of Tc, which suggests a correlation of {ie1345-3} with Tc. © 1990, Elsevier Science Publishers B.V.
