Investigations of the magnetic structure in the isotropic S = 1 kagome antiferromagnet ND4Ni2.5V2O7(OD)2.D2O

Abstract: Exotic electronic states are of great interest to fundamental science, such as the quantum spin-liquids (QSLs) which were theorised to behave like a sea of resonating spin states without preferential ordering, analogous to the liquid state. The best candidate materials for 2 dimensional QSLs are kagome magnets where the atomic magnetic moments make up a vertex-sharing lattice of triangles. Away from the quantum limit, semi-classical frustrated magnets are predicted to host novel ground states, including spin-liquid states. Here, we propose to study a new S=1 kagome antiferromagnet, ND4Ni2.5V2O7(OD)2.D2O, which shows evidence of competing magnetic interactions to produce an unconventional ordered ground state. We propose to use WISH to study short- and long-ranged spin structures and so to determine the role that frustration plays in its ground state properties.
