Title

Magnetic ordering in the quaternary chalcogenides Ba2FeMCh5 (M = Sb, Bi) (Ch = S, Se)

Abstract

This proposal is to explore the magnetic ordering present in a family of semiconducting quaternary chalcogenides containing Fe3+ ions. The compounds exhibit long range order with T_N ranging from 13K in Ba2FeSbS5 to 79 K in Ba2FeBiSe5, increasing by ~45 K as Se replaces S and by ~22 K as Bi replaces Sb. The spins are likely to order via unusually long Fe-Ch-M-Ch-Fe superexchange pathways, and neutrons are the key to establishing and comparing the long range magnetic structures and testing the computational explanation for the variation in T_N values.
