Magnetic susceptibility measurements of CrRh alloys are reported. Below the Néel temperature a temperature independent magnetic susceptibility is observed for the samples containing 10.9 and 14.5 at% Rh. A decrease of the magnetic susceptibility as a function of temperature is observed for samples containing between 5.14 and 14.5 at% Rh in the paramagnetic region. A slight localization, induced by Rh impurities on the host Cr atoms, is proposed in order to explain these peculiar behaviours. The magnetic phase diagram is also given. The Néel point rapidly increases at the beginning, with increasing Rh concentration, and then slowly decreases, giving rise to a large maximum at about 6 at% Rh.
