Abstract
We studied the magnetic susceptibilities parallel and perpendicular to the chain axis in TMNC in the temperatures ranges 20–13 K and 4.2–0.4 K. These experiments lead to TN=(1.195±0.005) K, J/kB=(1.09±0.10) K, D/kB=(2.10±0.46) K. Because of the ferromagnetic character of the intrachain exchange parameter, the dipolar interchain interaction is much more important in TMNC than in isostructural TMMC, as shown by our calculations. In TMNB, a transition to a 3‐d antiferromagnetic ordered state was found at TN=(2.680±0.010) K.Keywords
