Magnetic structure of the HoNiO3 perovskite - art. no. 144417

Neutron diffraction data collected on polycrystalline HoNiO3 have been used to investigate the magnetic behavior of the Ni and Ho sublattices in the m onoclinic insulating phase of this oxide. Different propagation vectors, k= (1/2,0,1/2) and k=0, are found for the Ni and Ho sublattices, respectively. Possible collinear and noncollinear magnetic ordering of the Ni moments ar e discussed, supporting the idea that even in the insulating phase, carrier s keep a certain degree of delocalization as a consequence of the strong p- d hybridization.
