By using the extraordinary Hall effect in SrRuO 3 films we performed measurements of the paramagnetic susceptibility in this itinerant ferromagnet, from T c (∼150 K) to 300 K. These measurements, combined with measurements of magnetoresistance, reveal that the susceptibility, which is almost isotropic at 300 K, becomes highly anisotropic as the temperature is lowered, diverging along a single crystallographic direction in the vicinity of T c. The results provide a manifestation of the effect of large magnetocrystalline anisotropy in the paramagnetic state of a 4d itinerant ferromagnet.
