Observation of field-split crystal electric field levels in CsErSe<sub>2</sub>

ORAL

Abstract

The rare-earth delafossite family has generated significant recent interests because of innately

frustrated triangular lattices and rich crystal electic field (CEF) physics. We present the compre-

hensive magnetic field dependent CEF spectrum using optical spectroscopy and magnetic prop-

erties of CsErSe2. We will discuss a unique method of determining the CEF Hamiltonian using

these results and its implications
