Abstract

The magnetic properties of YBa₂Cu₃O_z with different values of z in the temperature range 1.5-300 K were measured and compared with those of DyBa₂Cu₃O_z and EuBa ₂Cu₃O_z. The susceptibility data of YBa ₂Cu₃O_z and DyBa₂Cu₃O _z followed the Curie-Weiss law above T_c, while those of EuBa₂Cu₃O_z exhibited the Van Vleck and Frank behavior [Phys. Rev. 34, 1494 (1929)] with σ=33. The paramagnetism persisted even below T_c. The effective moment per copper ion increased as the oxygen content decreased. The results suggest that the paramagnetism in YBa₂Cu₃O_z originates mainly from the nonsuperconducting domains of the material which have disordered oxygen vacancies or have lower oxygen content than the superconducting ones.
