a Hall resistance as a function of magnetic field during cooling for T = 335 K (FM phase) and T = 227 K (AFM phase). b Hall resistance as a function of magnetic field during heating for T = 256 K (AFM phase) and T = 326 K (FM phase). c Temperature-dependent carrier density, n, obtained from the Hall measurements during cooling (blue) and heating (red). d Temperature-dependent effective mass, m*, obtained from the Hall-determined n and THz-determined \(n/{m}^{* }\) during cooling (blue) and heating (red).
