Exploring electronic and magnetic anisotropy with thermal expansion and uniaxial strain in CeRhIn<sub>5</sub>

ORAL

Abstract

The heavy-fermion material CeRhIn5 orders antiferromagnetically at 3.8 K in zero magnetic field. Recent high-field measurements discovered an electronic nematic-like state at 28 Tesla for fields applied at a slight tilt from the c-axis. Low-fields applied in the ab-plane also show a rich HT-phase diagram, where neutron scattering measurements have revealed a strongly field dependent spin anisotropy. Here, we explore the correlation between the high-field nematic phase and the low-field magnetic phases using a combination of thermal expansion and uniaxial strain measurements.
