Dynamical Ising-like model for the two-step spin-crossover systems
In order to reproduce the two-step relaxation observed experimentally in spin-crossover systems, we investigate analytically the static and the dynamic properties of a two-sublattice Ising-like Hamiltonian. The formalism is based on a stochastic master equation approach. It is solved in the mean-field approximation, and yields two coupled differential equations that correspond to the HS fractio...
متن کاملCoupled magnetic interactions and the Ising-like model for spin crossover in binuclear compounds
We introduced the technique of coupling of Ising-like spins in symmetric molecules in a way analogous to coupling of “real” spins known from the theory of quantum spin momentum. This new basis provides more natural and in some cases easier way of capturing the spin crossover behaviour of a binuclear system. We applied this general procedure on the simplest case of binuclear compounds where we t...
متن کاملLinear perturbation renormalization group method for Ising-like spin systems
The linear perturbation group transformation (LPRG) is used to study the thermodynamics of the axial nextnearest-neighbor Ising model with four spin interactions (extended ANNNI) in a field. The LPRG for weakly interacting Ising chains is presented. The method is used to study finite field para-ferrimagnetic phase transitions observed in layered uranium compounds, UAs1−xSex , UPd2Si2 or UNi2Si2...

متن کاملOn Two-parameter Dynamical Systems and Applications
In this note some useful properties of strongly continuous two-parameter semigroups of operators are studied, an exponential formula for two-parameter semigroups of operators on Banach spaces is obtained and some applied examples of two-parameter dynamical systems are discussed
