[(CH3)3NH]MnCI3.2H20, M= 257.45, orthorhombic, Prima, a = 16.779 (3), b = 7.434 (1), c = 8.227 (l)/~, V= 1026-2 A3, Qo= 1.67 (1) (by flotation in a mixture of CC14 and CH212), Qc = 1.666 gcm -3, Z=4, Mo K0q radiation, 2=0.70926 A,/z(Mo K~)= 19.13 cm -a, F(000)=516, final R=0.051 (all reflections) for the Caputo and Willett data set and 0.029 (observed reflections) for the Muir data set. The structure is comprised of infinite chains of edge-sharing MnCI4(OHz)2 octahedra separated by the trimethylammonium ions and discrete CI ions. It is, in fact, identical with that of the analogous Co compound with minor modifications produced by the difference in ionic radii of the two metal ions.

Magnetic phase diagram and first-principles study ofPb3TeCo3V2O14

et al. 2014

An antiferromagnetic ordering in Pb 3 TeCo 3 V 2 O 14 takes place through formation of short range correlation regime with T* ~ 10.5 K and succession of second order phase transition at T N1 = 8.9 K and first order phase transition at T N2 = 6.3 K. An external magnetic field rapidly destroys magnetic structure at T < T N2 and influences the magnetic order at T N2 < T < T N1 resulting in complex magnetic phase diagram of Pb 3 TeCo 3 V 2 O 14 as derived from magnetization and specific heat measurements. The first principles calculations indicate that in variance with layered crystal structure the magnetic subsystem of Pb 3 TeCo 3 V 2 O 14 is quasi-one-dimensional and highly unusual consisting of weakly coupled triangular tubes.

“…7 the inverse temperature dependences of the relaxation times in the logarithmic scale manifest a linear character for both relaxators. This allows determining the activation energy for each relaxator using the Arrhenius equation (3). The values of E r for high-frequency relaxator was found to be equal to 0.485 ± 0.005 eV (T < 250 K), 0.370 ± 0.005 eV (T > 250 K) and for the low-frequency relaxator -1.360 ± 0.005 eV.…”

Dielectric and Dilatometric Properties of NH(CH₃)₃CuCl₃·2H₂O Low Dimensional Ferroics

et al. 2004

View full text Add to dashboard Cite

On the basis of dilatometric and dielectric investigations of NH(CH3)3CuCl3 · 2H2O crystals the earlier unknown phase transition with considerable temperature hysteresis was found at T c 1 = 198 K and T h 1 = 223 K, respectively, in cooling and heating runs. Existence of the characteristic dielectric dispersion was revealed within the high-temperature phase. It corresponds to the single dielectric relaxator below 250 K as well as to co-existence of two relaxators above this temperature. The determined values of the activation energy and relaxation time are characteristic of the co-operative reorientation of the trimethylammonium cation (high-frequency relaxator) whereas the combined reorientation motions of the CuCl 2 · 2H 2 O chains would be responsible for the low-frequency relaxation process. It was found that the above mentioned quasi-Debye type processes are involved into the mechanisms of the protonic conductivity.
