Magnitudes S of Cu magnetic spins in La-systems were directly observed as a function of the Srand 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, S becomes large just at the concentrat
A structural transition at about 60 K occurs in La2\_,,Ba~CuO 4 only around x = 1/8, accompanied by suppression of superconducting transition temperature T o. Partial substitution of smaller divalent ions for Ba 2Γ· ions (Ba 2Γ· > Sr 2Γ· > Ca 2Γ· ) leads to suppression of this low-temperature structural
