Zusammenfassung:	Superconducting and paramagnetic contributions to the magnetization of polycrystalline Y 1− x Ho x Ba 2 Cu 3 O 7−δ samples were investigated. The superconductivity is responsible for a partial screening of magnetic ions from an external magnetic field and for a possible sinking of antiferromagnetic correlations between these ions. Magnetic moments of Ho ions influence on a peak effect induced by the order–disorder transition of the Abrikosov vortex lattice. The critical current density and the critical temperature of YBCO are not changed by the Ho doping.
