Excitations in a geometrically frustrated molecular magnet in a field: Mapping the wavefunctions across the avoided crossing.
Especially tantalizing molecular magnets are triangular antiferromagnetic (AFM) clusters, as they constitute the most basic geometrically frustrated magnet. We plan to do inelastic neutron scattering experiments on aligned single crystals containing an antiferromagnetic Cu(II) triangle to directly determine the tunnel splitting in a magnetic field. This tunnel splitting arises from a combination of Dzyaloshinkii-Moriya interactions and unequal exchange interactions in the presence of a magnetic field in the plane of the triangles.The proposed experiments will allow directly measuring the tunnel splitting at an avoided level crossing, as well as determining the wavefunctions of the involved states, resolving remaining questions concerning the spin Hamiltonian of this material.
