(a) Magnetization M(B) as a function of magnetic field B at various temperatures with B||c. (b) Field dependence of Hall resistivity r_yx(B) at various temperatures. The color code is the same as in (a). (c) The relationship between ρ_yx/B and ρxx2M/B at various temperatures. (d) Field dependence of different components of the Hall resistivity at 220 K. The blue, green, black, and red lines represent the measured ρ_yx(B), ρyxN(B), ρyxA(B), and ρyxT(B), respectively.
