Title

Oxygen content, ordering and magnetic structure in new oxygen deficient Sr(Sc/Ga)0.5Fe0.5O2.5+d

Abstract

The aim of the proposed experiments is to correlate oxygen content to magnetic structure in a new family of oxygen deficient perovskites SrSc0.5Fe0.5O2.5+d and SrGa0.5Fe0.5O2.5+d. On one hand, neutron diffraction will enable to investigate the nuclear structure of the two title compounds, with different oxygen stoichiometry (with d = 0, 0.125 and 0.25), and on the other hand, to explore the long-range magnetic structure of SrSc0.5Fe0.5O2.75 and SrSc0.5Fe0.5O2.75 between 2-25K.
