Abstract

We report a quantum oscillation study in the Dirac nodal-line semimetal candidate TaPtTe$_5$. The Fermi surface is probed via magnetic torque measurements with the magnetic field applied in the crystallographic a-b and b-c planes. The experimentally determined de Haas - van Alphen frequencies are consistent with results from band structure calculations. This study serves as an extension to the scarce quantum oscillation data on TaPtTe$_5$ currently present in the literature.
