Determination of the magnetic properties of nearly stoichiometric EuRh/sub 3/B2 on macroscopic and microscopic levels reveals that its ferromagnetism originates from the ordering of the spins of divalent Eu perpendicular to the hexagonal c aixs. This finding contradicts previous reports of Rh 4d-band itinerant-electron ferromagnetism and a nonmagnetic trivalent Eu state. The value of the /sup 151/Eu Moessbauer quadrupole splitting, e/sup 2/qQ = 48 +- 1 mm/s, is by far the largest ever reported for any Eu system and results from the extremely short Eu-Eu separation.
