Hall resistivity in MgO/Mn2CoAl/Pd trilayers. (a) The total Hall resistivity between 25 K and 350 K. The temperature in Kelvin is shown next to each curve, which are plotted with an arbitrary offset for clarity. (b) Detailed view around the compensation temperature. (c) At exactly the compensation temperature, the contribution of \({\rho }_{xy}^{T}\) stands out. (d) Temperature dependance of \({\rho }_{xy}^{T}\) and \({\rho }_{xy}^{A}\) showing an absence of any correlation between these two contributions to ρ xy . \({\rho }_{xy}^{T}\) is defined as the difference between the maximum of the THE peak, and ρ xy = 0. \({\rho }_{xy}^{A}\) is defined as the difference between ρ xy at 0 kOe after saturation at 3 kOe and ρ xy = 0.
