The temperature dependence of the DC susceptibility χ(T) is measured between 1.7 and 350 K on superconducting and nonsuperconducting bulk melt-processed (Nd0.33Eu0.33Gd0.33) Ba 2Cu3Oy by means of SQUID magnetometry. A strong superconducting contribution is found to coexist with a large paramagnetic moment provided by the Nd and Gd ions. The paramagnetic contributions measured on both types of samples follow a Curie-Weiss law; however, an antiferromagnetic ordering is not observed down to 1.7 K.
