Fig. 5

The Hubbard U dependence of a the magnetic momentum of Ni in (π, π, π) AFM phase, b the exchange coupling parameters, c specific heat (C) vs T with four J's, d the estimated TN with four J's, e specific heat C vs T with J1, J3 only and f the estimated TN with J1, J3 only. The shaded region in d highlights the possible TN of 70–90 K with a reasonable U = 5–6 eV.
