Abstract

The crystal and magnetic structures of Sr0.7Y0.3CoO2.62 were studied at high pressures up to 30 and 5 GPa by means of x-ray and neutron diffraction, respectively. An evidence for the pressure-induced change in the spin state of Co 3+ ions in octahedral coordination from intermediate spin to low spin was found from a behavior of Co-O bond lengths and obtained ordered magnetic moments values. The high spin state of the tetrahedral and five-coordinated Co 3+ ions in oxygen deficient layers remains stable under pressure. A rapid suppression of the initial G-type antiferromagnetic AFM state and a formation of the new AFM state with a propagation vector 1/2 1/2 1 was found. The possible mechanisms of the pressure-induced magnetic transformation are discussed.
