Ferroelectric order parameter in the two-particle cluster system near phase transition point: collective variables method

A new approach in the investigation of the order parameter behaviour near ferroelectric phase transition point is suggested. The short range and dipole interactions between particles are taken into account. The logarithmic corrections and effective critical exponents are calculated and discussed.Comment: 11 pages, 5 figure

Self-consistent approach to magnetic ordering and excited site occupation processes in a two-level system

Ferromagnetic ordering in a two-level partially excited system is studied in detail. Magnitudes of magnetization (magnetic order parameter) and lattice ordering (excited level occupation number) are calculated self-consistently. The influence of an external magnetic field and excited level gap on the ferromagnetic phase transition is discussed.Comment: 12 pages, 6 figure

Influence of boric anhydride upon the physical and chemical properties of ferrosilicon slag

The authors study the influence of boric anhydride upon the physical and chemical properties of slag in the manufacture of ferrosilicon. It is established that adding boric anhydride to the slag changes its refractory quality and its viscosity and eases pouring slag and metal. Slags with optimal composition and properties are described

Thermodeformational Behavior of Cubic Crystals of Sodium Cyanide

In the paper the authors provide results of the study of anisotropic and isotropic acoustic (elastic waves propagation velocities), dimensional (elastic moduli) and nondimensional (Poisson's ratios) elastic characteristics of mono- and polycrystals of sodium cyanide within the temperature range 283.7±473 K

Dipole glass parameter behaviour for ferro-antiferroelectric solid mixtures

A new definition of a dipole glass parameter for ferro-antiferroelectric solid mixtures is suggested. It is constructed on the nearest neighbours pair correlation functions for interacting dipole momenta. The behaviour of the dipole glass parameter is calculated and discussed.Comment: 8 pages, 3 figure
