Unusual Oscillatory behavior in the magnetothermal conductivity of NaErSe<sub>2</sub>

Oral-In-person

Abstract

The rare-earth delafossite family has generated recent interest as possible candidates for hosting a quantum spin liquid (QSL) phase. Delafossites have frustrated triangular layers  and strong spin orbit coupling, which manifests in rich crystal electric field (CEF) physics and large magnetic anisotropy. We report oscillatory behavior in the magnetothermal conductivity of NaErSe2, which is highly anisotropic and visible up to 40K. We will discuss possible origins for this oscillatory behavior and address contributions from the complex CEF landscape, which hosts multiple low-lying field-induced crossings.
