Title

Evolution of magnetic ordering in the layered oxide chalcogenides Ca2Fe2.7S2-xSexO3 x = 0.5, 1, 1.5

Abstract

This proposal follows a measurement of the magnetic ordering in Ca2Fe2.6S2O3 and preliminary measurements on the slightly more Fe-rich title compounds (Ca2Fe2.7S2-xSexO3 x = 0.5, 1, 1.5) which reveal complex and different evolution of the magnetic structures on the two mixed-valent iron sublattices through a series transitions below the onset of long-range magnetic order. The aim here is to make use of the high resolution of D1B in the long d-spacing region to determine the changing magnetic models and related these to the mixed-valence and the Fe deficiency in these compounds, and to compare the behaviour across the series.
