High Magnetic Frustration in a 2D Triangular Antiferromagnet

Abstract: Magnetic materials that only have significant interactions in one or two dimensions give rise to exotic magnetic states, particularly where they contain competing magnetic interactions that cannot be simultaneously satisfied, which is referred to as magnetic frustration. Magnetic materials that combine inorganic and organic components are ideally suited to hosting well separated sheets and chains in their structures. Recent measurements by our group have shown that (NH3NH2)2CoCl4(H2O)2, in which the molecular complex forms 2D layers built from edge sharing isosceles triangles of Co cations, is highly magnetically frustrated. This experiment will establish the ordered magnetic state in this material, that emerges below 200 mK, and probe its local magnetic structure at temperatures up to 20 K, where its magnetic interactions are significant but frustration prevents magnetic ordering.
