Abstract

By using the extraordinary Hall effect in SrRuO3 films we performed measurements of the paramagnetic susceptibility in this itinerant ferromagnet, from Tc (∼150K) to 300K. These measurements, combined with measurements of magnetoresistance, reveal that the susceptibility, which is almost isotropic at 300K, becomes highly anisotropic as the temperature is lowered, diverging along a single crystallographic direction in the vicinity of Tc. The results provide a manifestation of the effect of large magnetocrystalline anisotropy in the paramagnetic state of a 4d itinerant ferromagnet.
