“…In connection with this, we mention that in our previous work these excitations were found also by inelastic neutron scattering (high resolution neutron spectroscopy) on large single crystals of (NH 4 ) 2 MnF 5 , (ND 4 ) 2 MnF 5 and Na 2 MnF 5 [38,39,40], in good agreement with our Mössbauer-spectroscopic results [24,25,31,32]. …”

“…4, 5, and 6 show the results for best fits of (14) Considering (10) and (14), we can derive an expression calculating the magnetic susceptibilities of powder samples as is demonstrated for the case of (NH 4 ) 2 MnF 5 in Figure 9. The average magnetic susceptibility may then be written as In order to check our results discussed above we have started to perform inelastic neutron scattering experiments at the Hahn-Meitner-Institute at BER-II in Berlin to determine the magnetic linear [28] and non-linear excitations of (NH 4 ) 2 MnF 5 . However, the inelastic magnetic signals were weak and strongly hidden by the large incoherent background caused by the hydrogen atoms.…”

From the knowledge of the spin correlation functions derived from Mössbauer relaxation spectra of quasi-one-dimensional A 2 MnoyxFe ()() 2F< i (H20) we could fit the antiferromagnetic susceptibilities of A 2 MnF 5 (H 2 0) with A = Na , (NH 4 ) + , K + , Rb + obtained for single crystal samples. The calculation yielded characteristic parameters such as the local anisotropy D, the intra-chain exchange energy J, the inter-chain exchange energy \ J'\, the Neel temperature T N , and the spin canting angle (p.

Electron-spin-resonance (ESR) experiments have been performed on the quasione-dimensional magnet (NH 4 ) 2 MnF 5 . The ESR spectrum consists of two components, an extremely broad signal and a weak but sharp resonance on top of the broad signal. The resonance field of the dominating broad signal is most probably shifted by strong non-diagonal terms of the dynamic susceptibility to g-values well below g = 2 and becomes undetectable upon the onset of strong one-dimensional correlations below T 60 K. We attribute these two signals to Mn 3+ ions of the chains (broad resonance, intrinsic response of the sample) and to defects (small resonance), respectively. The ESR spectra reflect the evolution from the paramagnetic state (T > 60 K) to one-dimensional magnetic behaviour (T 60 K). The results are discussed with respect to the local anisotropy of the Mn 3+ ions and comparison is made with the behaviour of other one-dimensional magnetic compounds.
