A new crystal optical method for temperature measuring based on the sign inversion of birefringence ∆n and temperature dependence of ∆n(T) is substantiated. The respective characteristics of some crystals are presented, which ...

We present a general approach to the problem of a ferromagnetic phase transition in diluted magnetic semiconductors. The Curie temperature of ferromagnetic transition is calculated in the mean field approximation. It ...

Within the model proposed earlier, we study the effect of hydrostatic pressure on relaxational dynamics of deuterated KD₂PO₄ type ferroelectrics. Within the four particle approximation for deuteron ordering model and ...

Mykhailo Kozlovskii is a renowned Ukrainian physicist, doctor of physico-mathematical sciences, deputy head of the Department of Condensed Matter Statistical Theory of the Institute for Condensed Matter Physics of the ...

Nearly free electron model is used for the s-electron subsystem of liquid transition metals. d-electrons are considered to be bound and serve as an additional scattering factor. Model Hamiltonian of the electron ...

The static and dynamic dielectric susceptibility of the pseudospin-electron model is investigated in the random phase approximation. The possibility of the phase transition to the homogeneous phase, to the phase with ...

The present article deals with the investigation of structure factor, s(q) ; radial distribution function, g(r) and interatomic distance, r₁ of liquid rare earth metals, Nd, Dy, Ho, Er and Lu by adopting Charged Hard ...

Within the framework of the proton model we study thermodynamic and static dielectric properties of the ADP type antiferroelectrics with taking into account the tunnelling effects of protons on hydrogen bonds. In the ...
