Abstract

We discuss recent soft x-ray resonant diffraction studies of magnetic and structural correlations in manganites and cobaltates. In half-doped manganites, the resonant enhancement of super-lattice diffraction peaks resulting from orbital and magnetic order is utilized to make a direct comparison of orbital and spin correlations. The main finding is that the correlation length associated with magnetic order exceeds that of the orbital order by of order a factor of two--a result which appears at odds with orbitally driven magnetic exchange pathways. Similar resonant diffraction measurements at the Co L-edge were performed to study the oxygen-doped cobaltate Bi₂Sr₂CoO_6+δ, in which we find a surprising incommensurate antiferromagnetic order.
