Electronic structure in a rare-earth-based antiferromagnet TbNi<sub>3</sub>Ga<sub>9</sub>

ORAL

Abstract

Rare-earth-based intermetallics provide flexibility to study the electronic, magnetic, superconducting, and topological properties by tuning the crystal structure, composition, and spin-orbit coupling. Recently, RNi3(Ga/Al)9 intermetallic materials have been studied for their richness in crystal, magnetic, heavy fermion, and quantum criticality behaviors. However, momentum-resolved electronic structure studies of such systems are lacking. Here, we present electronic structure study of TbNi3Ga9, both above and below the Neel temperature, carried out with angle-resolved photoemission spectroscopy measurements in conjunction with density-functional theory calculations as well as electric, magnetic, and thermodynamic measurements. This study will open up exciting avenues towards exploration of electronic properties in the chiral family of RNi3(Ga/Al)9 materials with wide range of intriguing properties.
