a Temperature dependence of resistance normalized to the 300 K value in the transition region. Inset, overview from room to low temperature. b Magnetization as a function of temperature measured in an out-of-plane magnetic field in ZFC and FC conditions. Inset, overview from room to low temperature. Vertical black lines in panels (a), (b) are drawn at the correspondence of the antiferromagnetic transition or the ferromagnetic-like one at T = 12.4 K and T ≈ 5 K. c Magnetic field dependence of the Hall resistivity measured for 4.8 K < T < 30 K. d The Magnetization as a function of the out-of-plane magnetic field for T = 5 K, 10 K, 30 K applied in the out-of-plane direction. Vertical black lines in panels (c), (d) are drawn at the correspondence of the spin flop transition (B ≈ 0.04 T) at T = 10 K and the saturation field (B ≈ 0.1 T) at T = 5 K.
