Fig. 2: Anomalous Hall resistance, magnetization and magnetic structure of 24-SL MnBi2Te4.
From: Topological response of the anomalous Hall effect in MnBi2Te4 due to magnetic canting
a Rxy measured in samples A, B and C at 4.2 K. b Anomalous Hall resistance \(R_{xy}^A\) (red at 1.4 K) measured in sample A compared to its magnetization (blue at 2 K). Labels (i–v) mark 5 different magnetic regimes discussed in the text. \(R_{xy}^A\) is obtained by subtracting the high field linear Hall effect from \(R_{xy}\). c Magnetization measured in sample A at 2 K and 5 K using two different instruments (see methods) compared with calculated magnetization using the modified Mills model (red) and Monte Carlo simulations (blue). d Evolution of the spin texture of the 24-SL system as a function of magnetic field, obtained from Monte Carlo simulations at 2 K. Regions (i–v) correspond to the 5 magnetic regimes observed in (b). The color of the arrows represents the magnitude of the z-component (fully up: red, fully down: blue).
