“…2, 3). The same phenomenon has been encountered by other authors [21]; in particular, this may account for the anomalous peak observed in the specific heat) measurements of the compound slightly below the magnetic ordering temperature [18,21] since our measurements show that both structures order magnetically between 4.2 and 1.5 K.…”

A comparative investigation of the 67Fe absorption and emission spectroscopy data in hosts of CoFz, CoC1,-2py, and FeCI,-2py is reported in both the paramagnetic and antiferromagnetic phases of these compounds. The electron capture decay products are observed to coexist in the Fez+ and Fe3+ ionic configurations in CoF,, while only the Fez+ charge state is stabilized in FeC1,-2py and CoC1,-2py hosts. Distributions of hyperfine interactions are observed in the complex ligand compounds FeCIz-2py and CoC1,-2py, whereas there is no indication for such effects in the monoatomic ligand compound CoF,. This indicates unique unperturbed substitutional rest sites in CoF,, whereas in the other hosts, part of the decay products are observed in a distribution of defect sites.Une etude comparative des spectres Miissbauer de 57Fe en kmission et en absorption dans let matrices CoF,, CoC1,-2py et FeCL-2py a 6th realisee B la fois dans les phases paramagnetique es ordonnee de ces composbs. Dans CoF,, les atomes de 57Fe Crees par capture Blectronique coexistent dans les configurations Fez+ et Fe3+, tandis que dans FeClZ-2py et CoC1,-2py, seul 1'6tat divalent Fez+ est observe. Dans les composes B ligands complexes FeC1,-2py et CoCI,-Spy, une distribution de parametres hyperfins est mesurke; par contre, dans le compose B ligand monoatomique CoF,, il n'existe aucun argument en faveur d'une telle distribution. Les rbsultats suggkrent que, dans CoF,, les atomes nuclkoghes resident dans des sites de substitution uniques non perturbks, tandis que dans les autres composes, les produits de decroissance presentent une distribution de dkfauts P tructnraux.

“…Similarly, the powder susceptibility measurement of CoCl 2 Á 2NC 5 H 5 shows that it can be treated as a quasione dimensional spin-1 2 Ising ferromagnet [120]. The average susceptibility of this quasi-1D compound is calculated with g ¼ 5:49 [122], which is shown in Fig. 15.…”

“…The inset of Fig. 10b shows a C/¹ versus ¹ plot for x"0.75, which shows an almost linear behavior as ¹ approaches zero, although a sudden jump follows below 2.4 K. Speci"c heat for 1D HAF chains is generally approximated to take the form C" ¹ at low temperature (¹J/k ) (11). The actual C is the sum of the magnetic and lattice contributions; C" ¹# ¹.…”
