Abstract

Results of neutron diffraction and bulk magnetic measurements on powder samples Ho_0.1Sr_0.9CoO_3-x as a function of oxygen deficiency 0.15<x<0.49 are given. It is found that the oxygen non-stoichiometry affects the crystal and magnetic structures as well as the value of the magnetic moment, and strongly modifies the magnetic ordering temperatures.
