a Total \(S_{xx}\) (left-hand side, LHS) at various temperatures as a function of magnetic field and its transverse component \(- \alpha _{xy}\rho _{xy}\) (first term on the right-hand side, RHS) and longitudinal contribution \(+ \alpha _{xx}\rho _{xx}\) (second term on the RHS). b Total \(S_{xx}^2/\rho _{xx}\) (LHS) at various temperatures as a function of magnetic field and its transverse component \(+ \alpha _{xy}^2\rho _{xy}^2/\rho _{xx}\) (first term on RHS), longitudinal contribution \(+ \alpha _{xx}^2\rho _{xx}\) (second term on the RHS), and the cross-term \(- 2\alpha _{xy}\alpha _{xx}\rho _{xy}\) (third term on the RHS). The dominant contribution of transverse component can be seen at all temperatures.
