“…Note that the optical spectrum of the two compounds is almost identical, except for the fine-structure splitting of some d-d transitions, which is however too tiny to be resolved by broadband femtosecond laser pulses. 37 Consequently, a straightforward comparison of the results obtained with these two samples can be carried out only based on their magnetic properties. Figure 7(a) reports the temperature dependence of the spin dynamics optically excited and detected in the time-domain in K 2 NiF 4 .…”

“…The dominant exchange interaction determines an antiparallel alignment of the Ni 2+ spins in the NiF 2 planes, via 180 • Ni-F-Ni bonds. 36,37 Even neglecting the interplane exchange interaction between the Ni 2+ ions in the ordered planes and the isolated Ni 2+ ion between the planes (which is at least one order of magnitude weaker than the in-plane exchange coupling 36 ), the bulk properties of this compound are properly described.…”
