XMCD and magnetism of the ferrimagnetic system NaV6O11

We investigated the XMCD signal at the V L-2.3- and the O K- edges. Sum rul es exhibit that NaV6O11 is mainly a spin magnet with a small contribution o f an orbital moment, but due to the small spinorbit splitting of the V L-2, L-3-edges a direct extraction of the magnetic moment is problematic. We can identify two antiferromagnetically coupled sub bands. Ferromagnetic correl ations were observed along one direction. The electronic transport properti es are dominated along the easy axis in the canted ferrimagnetic low temper ature structure.
