摘要:
AbstractA simple force constant model is used to calculate the normal mode frequencies and eigenvectors of the carbon disulphide crystal. By adjustment of three intramolecular and four intermolecular parameters, good agreement with spectroscopic data is obtained for the lattice mode frequencies and for the crystal field splittings of the molecular modes.

摘要:
AbstractThe EPR is studied of FAcentres in CaF2:Li+, CaF2:Na+, and SrF2:Na+. In CaF2:Li+, the spectrum is very similar to that of F centres in pure CaF2: the superhyperfine coupling constant with lithium is unmeasurable. On the other hand, in CaF2:Na+and SrF2:Na+, the superhyperfine coupling with a sodium nucleus is noticeable. The EPR of so‐called “F2A” centres in the same matrices is also observed, which corroborates our previous magnetic circular dichroism conclusions: “F2A” centres do not correspond to two electrons in two adjoining anion vacancies with a substitutional sodium in close vicinity. From the observed superhyperfine structure, it is not yet found what is the genuine microscopic structure of these “F

摘要:
AbstractIt is demonstrated that the diffusion model proposed by Varotsos and Alexopoulos implicitely includes a correlation between diffusion energyHand entropySanalogous that deduced by Wert and Zener. For the impurity diffusion via vacancies this correlation betweenHandSis not correct. Thus, the model of Varotsos and Alexopoulos is not applicable to the impurity diffusion. For self‐diffusion the model roughly approximates the temperature function of the diffusion coefficientD0, however, it is unable to describe the curvature of the Arrhenius plot ofD

摘要:
AbstractFor Ising ferromagnets withS= 1,S= 3/2, andS= 2, the magnetization 〈Sz〉 and the Curie temperatureTCare calculatded with the use of pair mode lapproximation. Assuming the bilinear and biquadratic exchange interactions (JandJ′) between nearest‐neighbouring pair of spins and the uniaxial single‐ionic anisotropyDfor each spin, the behaviours of 〈Sz〉 andTCas a function of these exchange parameters and the uniaxial anisotropy parameter are investigated for the Ising spin systems with various value
