“…However, such bridging ligands are missing in DHN. Similar situation is found in some weakly frustrated pyrazine-based copper complexes, in which the orientation of the magnetic d x 2 −y 2 orbit occupying the basal planegives a direct overlap with the ligand orbit of the pyrazine unit along the side of the square[28][29][30][31][32][33]. The absence of the orbital overlap along the diagonal suggests that DHN is free…”

“…The nonmonotonic field dependence of the ordering temperature has been reported in many quasi-2D magnets [32,33,47,48], and it was proposed to originate from the 2D quantum fluctuations even though the interlayer interaction is relatively strong [47,49].…”

“…Such extreme spatial two-dimensionality accompanied by the absence of the λ-like anomaly in the specific heat in zero magnetic field was already experimentally observed in Cu(tn)Cl 2 (tn = C 3 H 10 N 2 ) [89] (Figure 9b) and Cu(pz) 2 (pyO) 2 (PF 6 ) 2 (pyO = pyridine-N-oxide) [90]. Thus, one has to be careful in the declaration of the absence of the 3D LRO on the basis of the specific heat only and other experiments are necessary to confirm the assumption.…”

“…When the field was applied perpendicular to the easy plane, in accord with the theory [99], the field plays a role of an effective easy-plane anisotropy, thus fingerprints of the BKT transition in the whole field region up to B sat can be expected. Considering the field applied within the easy plane, authors expected a field-induced easy-axis anisotropy, established in the fields up to 5 T [90]. In these fields, the formation of tiny λ-like anomalies, typical for the Ising transitions was observed, while at the fields above 5 T, the anomalies evolved to a broad anomaly of the expected BKT type and the system behaved as the isotropic 2D HAF in the field.…”
