Anomalous Hall Effect in topological Heusler semimetal ZrCo2Sn.

ORAL

Abstract

Besides non-magnetic Weyl semimetals without inversion centers, Weyl Fermions are also predicted to exist in certain topological materials with time-reverse symmetry breaking. Due to the topological non-trivial state, the system exhibits novel properties compared to the normal metal. In this talk, we will present the systematic magneto-transport study on the magnetic Heusler ZrCo{\$}\textunderscore 2{\$}Sn single crystal, a proposed candidate of ferromagnetic Weyl semimetal. Ruderman--Kittel--Kasuya--Yosida (RKKY) picture will be discussed regarding the isotropic negative magnetoresistance observed.
