Fig. 3: Magnetization and anomalous Hall effect of Mn5Si3.
From: Anomalous Nernst effect in the noncollinear antiferromagnet Mn5Si3
a Magnetization M(H) at T = 35 K. Insets show a close up of M(H) near zero field and around the transition at Hc1. b Remanent field MR(0) and magnetization jumps ΔM(Hc1) and ΔM(Hc2) obtained from M(H) vs temperature. Closed (open) circles indicate data obtained after applying a magnetic field of ± 5 T ( ± 2 T) before measuring MR(0). The accuracy with which the values from M(H) loops could be determined is indicated by error bars. c–f Anomalous Hall effect for various temperatures. g Anomalous Hall conductivity σxy(H) at T = 25 K. Open symbols represent data in the virgin magnetic state before sweeping the field from zero to +8 T. h Temperature dependence of σxy(0) and σxy(Hc1). Inset shows the resistivity ρxx(T) with indicated Néel temperatures TN1 and TN2 at the magnetic phase transitions AF1/AF1' and AF1'/AF2, respectively. The magnetic field was always oriented along the crystallographic c axis.
