Abstract
TaRhTe is a type-IIWeyl semimetal, exhibiting fourWeyl points in proximity to the Fermi level. In this article, we report our results of a systematic study of longitudinal magnetoresistance in TaRhTe. Our findings indicate that magnetoresistance becomes negative only when the magnetic field is applied parallel to the electric field. By rotating E (as well as B), we show that its origin is consistent with the prediction of the chiral anomaly, while the current jetting effect and weak localization could be excluded. The negative magnetoresistance persists up to room temperature, suggesting that TaRhTe4 exhibits distinctive properties within the family of Weyl semimetals.
