Figure 2

Anisotropic isothermal magnetization for Co4Ta2O9. (a) Isothermal magnetization, M, measured at 2 K in the H range of ± 9 T along the a, b* and c axes. (b) Magnified plot of M for the a direction. Short-dotted vertical lines indicate spin-flop transitions occurring at HC ≈ ± 0.3 T. (c) Antiferromagnetic spin structure of Co2+ ions at H = 0 T (Top). Magnetic structure of Co2+ moments above the spin-flop transition, H > HC along the a axis (bottom).
