Electronic and magnetic properties of the 4d itinerant ferromagnet SrRuO3

Density functional calculations are used to elucidate the electronic and magnetic structure of SrRuO3. Itinerant ferromagnetic behavior is found both in the cubic perovskite and the actual orthorhombic structure. The calculated moment is 1.59 μB. Unusually strong hybridization is evident in both the electronic structure and magnetism. The Fermi velocities indicate significant spin differentiation of the transport properties.
