a The real part of the AC susceptibility (χ′) of polycrystalline, orthorhombic barlowite 1 and a collection of single crystals of hexagonal barlowite 2. b The real part of the AC susceptibility (χ′) of a 2.0 mg single crystal of barlowite 2 aligned in the ab plane and along the c-axis. c Aligned magnetization (M) as a function of applied field at T = 2 K for single crystals of barlowite 2 and 1 (from ref. 32). d Heat capacity associated with the magnetic transitions (Cmag) of barlowite 2 calculated as C − Cbg (Supplementary Fig. 16). The dashed black lines denote the magnetic transitions of barlowite 2: TN1 = 10 K and TN2 = 6 K. Error bars represent the confidence interval in the fitting procedure corresponding to ±σ (σ is the standard deviation). Note: 1 emu (mol Oe)−1 = 4π10−6 m3 mol−1.
