Neutron scattering and thermodynamics studies of new Tb and Er based Shastry Sutherland Lattice compound.

ORAL

Abstract

In two -dimensional magnetic compounds, the Shastry-Sutherland lattice (SSL), an orthogonal arrangement of dimers with antiferromagnetic interdimer coupling J′ and the intradimer coupling J, have attracted attention due to their complex phase diagrams, displaying a variety of magnetic phases in magnetic fields and pressure; such as dimer state, plaquette state, fractional magnetization plateaus, and crystals of bound states. We have synthesized single crystals of a new family of Tb and Er-based SSL compounds and characterized them using thermal, magnetic, and neutron scattering measurements. In this talk, we are going to present our results for these compounds.
