Synthesis and Characterization of Rare-Earth Based Triangular Antiferromagnet Borates

ORAL

Abstract

Recently, triangular antiferromagnetic materials have attracted attention because competing interactions on the lattice can give rise to exotic phenomena, such as Quantum Spin Liquids. We have initiated systematic efforts to synthesize single crystal samples of a family of rare-earth based triangular antiferromagnet borates. We have used x-ray diffraction as well as thermal and magnetic measurements to characterize these compounds. Additionally we have carried out neutron scattering experiments to probe the static and dynamic properties of these systems. In this talk, we will present the results of our experimental efforts.
