Magnetotransport under pressure in helical magnet Au2Mn

ORAL

Abstract

The binary compound $Au_{2}Mn$ is well studied because of its magnetic spiral structure. This material is also known to have temperature-dependent giant magnetoresistance. We measured the magnetoresistance and Hall effect as a function of both temperature and pressure. Results will be discussed in relation to neutron diffraction under pressure and the stability of the helical phase.
