Fig. 2: Longitudinal magnetoresistance of HoAuSn.

The temperature dependence of the longitudinal resistivity \({{{{{{\rm{\rho }}}}}}}_{{{{{{\rm{xx}}}}}}}\) at several magnetic fields. The upper inset shows the sample geometry where the electric current and the magnetic field are along [\(1\bar{1}0\)]. The lower inset shows the magnetization (M) dependence of the resistivity ratio \({\rho }_{{xx}}\)(M) / \({\rho }_{{xx}}\)(0) at several temperatures. The dashed line denotes the relation that \({\rho }_{{xx}}\)(M) / \({\rho }_{{xx}}\)(0) = 1- C(M-Ms)2, with C = 4 and Ms being the saturation magnetization.
