Fig. 3: Magnetization data for Ba3Er(BO3)3.
From: Realization of two-sublattice exchange physics in the triangular lattice compound Ba3Er(BO3)3

a Isothermal magnetization data of Ba3Er(BO3)3 taken at various temperatures. Closed points show data with field applied in-plane and open points show data with field applied along the c-axis. The different colors indicate the temperatures of the measurements. b First derivative of isothermal magnetization with field applied along the c-axis showing anomaly between 1 T and 3 T, with colors representing the same temperatures as in a.
