Abstract

Abstract : With the rising interest in organic based materials for spintronic and multiferroic applications it is important to fully understand their electrical and magnetic properties and to identify correlations between their structural and physical attributes. In this work we look at a TCNQ based charge transfer compound to provide insight into the low temperature magnetism. Abstract : With the rising interest in organic based materials for spintronic and multiferroic applications it is important to fully understand their electrical and magnetic properties and to identify correlations between their structural and physical attributes. One material that still holds some ambiguity is triethylammonium bis-7, 7, 8, 8-tetracyanoquinodimethane (TEA(TCNQ)2 ). This charge transfer compound has one electron delocalised across two TCNQ molecules along quasi-1D stacks. Previous work has shown that there is magneto-electrical coupling associated with the magnetic transition at ∼120 K, however the magnetism and magnetic ground-state are not well understood. Within this manuscript we provide evidence for a long range magnetic order that is 3D in nature.
