Investigation of a new three-dimensional frustrated quantum magnet

Abstract: Interesting behaviour in Heisenberg spin systems originates from networks of triangles or tetrahedra, where spins interact via antiferromagnetic interactions. In 3D there are many well-known examples of networks of corner-shared tetrahedra, 3D networks of corner-sharing triangles are much less explored although they would also give rise novel states. Here we will investigate a new compound where spin-1/2 ions are coupled by several exchange interactions. The 1st neighbour interaction couples them into isolated triangles. The 2nd neighbour interaction gives a hyperkagome lattice - network of corner sharing triangles, and the 3rd neighbour interaction gives uniform chains. Together these interactions create a highly frustrated 3D network. In this proposal we plan to measure the magnetic excitation spectrum to identify the underlying excitations and determine the interactions.
