Spin density distribution in untwinned ferromagnetic SrRuO3
SrRuO3 is the perovskite member of the well known Ruddlesden-Popper series of ruthenates Srn+1RunO3n+1. It is the only simple material (otherwise one has to study three or higher-number layer members of the Ruddlesden-Popper series) that exhibits ferromagnetic order at ambient conditions. Magnetic hysteresis loops reveal strong anisotropic properties which are only accessible with twin-free crystals. We recently succseed in obtaining them by applying uniaxial pressure during cooling through the structural phase transitions. Such strong magnetic anisotropy can only result from some orbital preference rendering a more deep analysis of the spin density desirable. Also in view of the nearly half-metallic character it would be very interesting to resolve the orbitals carrying the magnetic moment in SrRuO3.
