Magnetic ground state and the spin-state transitions in YBaCo2O5.5.

Original language description

The crystal and magnetic structure of the perovskite-like, oxygen deficient cobalt oxide YBaCo2O5.5 has been studied by means of neutron and X-ray diffraction in the 10?300 K temperature range. The magnetic ground state is characterized by a coexistenceof two distinct antiferromagnetic phases. In the first one, the ionic moments of high-spin Co3+ ions in the pyramidal sites are ordered in a spiral arrangement, while octahedral sites are non-magnetic due to presence of low-spin Co3+ ions. The arrangement in the second phase is collinear of the G-type, with non-zero moments both in pyramidal (high-spin Co3+ ions) and octahedral sites (presumably a mixture of the low- and high-spin states).
