Orbital and magnetic ordering in La0.5Sr1.5MnO4 studied by soft X-ray resonant scattering -: art. no. 214421

Orbital and magnetic ordering in La0.5Sr1.5MnO4 have been studied with resonant soft x-ray scattering at the Mn L-2,L-3 edges and for the first time azimuthal angle scans and polarization analysis are presented. The azimuthal angle dependencies are well described by the occurrence of a quadrupole (orbital) ordering below T-OO and an additional dipole (magnetic) contribution below T-N. There are no indications that there is an enhanced Jahn-Teller distortion at T-N as reported in a previous study. Subsequently, it is shown that there is simultaneous ferro- and antiferromagnetic ordering along the c-direction.
