a Magnetic field-dependent unconventional anomalous Hall resistivity (\({\rho }_{xy}^{{{{{{{{\rm{T}}}}}}}}}\)) at different temperatures. Below T = 25 K, \({\rho }_{xy}^{{{{{{{{\rm{T}}}}}}}}}(H)\) shows a positive hump, which disappears completely at T = 25 K. Near TN, \({\rho }_{xy}^{{{{{{{{\rm{T}}}}}}}}}\) at high magnetic fields grows rapidly, followed by its suppression at high temperatures. b Temperature-dependent \({\rho }_{xy}^{{{{{{{{\rm{T}}}}}}}}}\) at H = 17.5 T. At T ~ 25 K, \({\rho }_{xy}^{{{{{{{{\rm{T}}}}}}}}}\) shows a sign-change from the positive (blue shaded) to the negative (red shaded) and a strong deep immediately above TN.
