Zusammenfassung:The body centered tetragonal ErRh4B4 compound undergoes an itinerant ferromagnetic transition at Tm=21 K characterized by a susceptibility equal to the inverse of the demagnetizing coefficient. The itinerant ferromagnetism does not prevent the simultaneous presence of the superconductivity from 7.7 K down to 0 K. The diamagnetic ac susceptibility can be calculated from the ferromagnetic one. The coexistence of itinerant ferromagnetism and superconductivity among d electrons would be one of the most convincing arguments in favor of ‘‘odd-parity’’ superconductivity.
