Extended Data Fig. 7: Bulk magnetization data with B∥c.
a, Curie-Weiss fit of magnetic susceptibility χ = M/H, measured with 0.1 T external magnetic field applied along the c-axis. b, M(H) curves obtained at constant temperatures T as indicated in the panel. c, Magnetization isotherm and its corresponding field derivative at T = 2 K. The dashed vertical line, labelled as Bc1, represents the hysteretic boundary between Phase-I and Phase-II. Around this region, ramping up and ramping down direction of external magnetic field is indicated by solid and dashed arrows, respectively. d, Derivative of magnetization with respect to applied field at various T, showing peak-like features at Bcoerc (red arrow) and Bc1 (black arrows) defined in Fig. 4a. Consecutive curves are shifted by 0.2 μB f.u.−1 T−1 for better visibility. Similar to Panel-c, solid and dashed lines denote the direction of magnetic field ramping. e, Temperature dependent derivative dM/dT of magnetization data measured at constant magnetic field, showing two clear transitions, TN1 and TN2 as defined in Fig. 3. Each consecutive curve is shifted by 0.002 emu mol−1 K−1 for better visibility. Inset: Zoom-in of data at low magnetic field.
