Magnetic Hamiltonian of the S=1/2 kagome antiferromagnet Cd-Kapellasite

Abstract: In everyday life, we often experience frustration from not being able to reach our goals; similarly, in physics and chemistry, frustration is caused by the inability of a system to satisfy all of its internal interactions. Frustration is most commonly observed in magnetic materials, where it is caused by either the geometry of the magnetic lattice or competing interactions. These systems are predicted to manifest many interesting phenomena, most notably exotic states called a quantum spin liquids. In this proposal, we aim to study the magnetic excitations of candidate for such a state, Cd-kapellasite. While the material shows conventional long range order at zero magnetic field, frustration stabilises a number of unusual quantum states in a field. To understand these, we need to understand the internal interactions of the system, for which we request beam-time on the LET spectrometer.
