Magnetism of matters has two basic ingredients. While exchange and correlation are responsible to the stability of magnetic moment, magnetic ordering is controlled by orbital hybridization, which depends on the atomic arrangement and the mode of orbital occupation. Transition-metal oxides serve as a
Resonant soft X-ray Bragg diffraction is used to probe the magnetic and possible orbital ordering below the metal-insulator transition in the NdNiO 3 . Preliminary measurements, performed at the Ni L 2;3 edges, suggest the absence of orbital ordering at T MI . The observed signal probes the magnetic
