a, b, Temperature dependence of the specific heat, C, divided by T for H ∥ a (a) and H ∥ b (b). Arrows indicate the Néel temperature TN. c, Field dependence of TN for H ∥ a and H ∥ b, determined by the specific heat measurements. TN, determined from the thermal conductivity and magnetic susceptibility26, is also shown. The critical field for H ∥ a is slightly lower than that for H ∥ b, but both phase diagrams are very similar.
