Neutron scattering and thermodynamics studies on Er-based Ising Shastry Sutherland Lattice compound.

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 Er-based SSL compound and characterized them using thermal, magnetic, and neutron scattering measurements. In this talk, we will present our results in understanding the multiple magnetization plateaus hosted by this system
