The study of phase transitions in an ordered cubic nanoparticles 2D array was carried out by computer modeling. performed for the Ising model. Wolf cluster algorithm is used to simulate transition system. interaction between exchange. spins different particles less one particle. Cases energy values are considered. single-domain. ferromagnetic investigated. total magnetization system as order parameter. temperature calculated based on finite dimensional scaling theory using Binder cummulants....
Subject of research: the article presents studies properties solid solutions V2Me0,02O3 in metaldielectric phase transition region.
 Purpose to obtain temperature dependences physical parameters (heat capacity, electrical resistance, magnetic susceptibility) samples composition range 60-400 K; determine effect vanadium concentration and type alloying element on energy spectrum crystal lattice.
 Methods objects research were based oxide V2O3, alloyed with aluminum, iron, chromium....
The paper presents the results of a study temperature dependence molar heat capacity at constant pressure in range (from 5 to 300 K) for vanadium-based materials. For all studied materials, values density States near Fermi level are calculated. It was found that V3Si and V3Ge state μ( E ) correlate with transition temperatures superconducting state. materials V2O3 V1.973Me0.027O3 (Me - Al, Fe, Cr), it metal-dielectric phase transitions decrease increasing States.
