Design and Synthesis of Novel Quantum Magnets

POSTER

Abstract

Due to recent advances in the field of topological quantum spin liquids, there is an increasing demand for high quality single crystals of frustrated magnets that host such exotic behavior. Here we present our recent results of such efforts. Solid-state reactions are used to synthesize polycrystalline samples of quasi-2D and 3D frustrated quantum magnets, whose purity is confirmed by powder x-ray diffraction analysis. With a pure polycrystalline sample, the optical floating zone and chemical vapor transport techniques are used to produce high quality large single crystal samples. We use an array of thermal and magnetic measurements as well as single crystal x-ray diffraction to characterize the samples, before performing advanced neutron and synchrotron x-ray scattering experiments at national user facilities.
