Abstract
The temperature dependence of the DC susceptibility chi (T) is measured bet ween 1.7 and 350 K on superconducting and nonsuperconducting bulk melt-proc essed (Nd0.33Eu0.33Gd0.33) Ba2Cu3Oy, by means of SQUID magnetometry. A stro ng superconducting contribution is found to coexist with a large paramagnet ic moment provided by the Nd and Gd ions. The paramagnetic contributions me asured on both types of samples follow a Curie-Weiss law; however, an antif erromagnetic ordering is not observed down to 1.7 K.
