PACS. 64.10.+h – General theory of equations of state and phase equilibria. Abstract. – A density functional theory of two-dimensional freezing is presented for a soft interaction potential that scales as inverse cube of particle distance. This repulsive potential between parallel, induced dipoles is realized for paramagnetic colloids on an interface, which are additionally exposed to an extern...

Using an effective field theory with correlations we study a diluted mixed spin-112 and spin-312 Ising ferrimagnetic system with a crystal field interaction D(D < 0) on a honeycomb lattice. We find that the system may exhibit two compensation points in the total magnetization curve, although the corresponding system in the absence of dilution or with D = 0 never exhibits any compensation point ...

New observable integer-valued numbers of the topological origin were revealed by the present authors studying the conductivity theory of single crystal 3D normal metals in the reasonably strong magnetic field (B ≤ 10 3 T l). Our investigation is based on the study of dynami-cal systems on Fermi surfaces for the motion of semi-classical electron in magnetic field. All possible asymptotic regimes...

We present a general Ginzburg-Landau theory of electrostatic interactions and electric field effects for the order parameter, the polarization, and the charge density. Electric field effects are then investigated in near-critical fluids and liquid crystals. Some new predictions are given on the liquid-liquid phase transition in polar binary mixtures with a small fraction of ions and the deforma...

The results of ESR measurements on a single crystal of the spin-Peierls compound CuGeO3 doped with 4% Zn are reported. We have observed, for the first time, ESR signals in the antiferromagnetic phase below the Néel temperature(TN = 4.2 K). The excitation energies at zero field are 26.4 and 40.6GHz. The frequency versus magnetic field relation of these ESR signals is well explained by the theory...

Modeling of spin Hamiltonian parameters enables correlation of crystallographic, spectroscopic, and magnetic data for transition ions in crystals. In this paper, based on the crystallographic data and utilizing the point-charge model and superposition model, the crystal field parameters (CFPs) are estimated for Ni2+(3d8) ions in the Haldane gap system Y2BaNiO5. The CFPs serve as input for the p...
