  1. All theoretical results are obtained in the mean-field approximation using exchange parameters from NSC, NSC-F and SC calculations. Note that the mean-field approximation typically overestimates the \(T_{C}\) by \(\sim\) 15%. The exchange parameters of Ref.52 are obtained using the MFT approach of Liechtenstein et al.9 in the LWA.
