Modified Monte Carlo method with thermostat algorithm for model orthonickelates
V. S. Ryumshin, Yu. D. Panov, V. A. Ulitko +1
The results of numerical simulation using a modified Monte Carlo method with a thermostat algorithm for a pseudospin model of orthonickelates are presented. Temperature phase diagr…
The Monte Carlo Method for the Orthonickelate Model
Yu. D. Panov, S. V. Nuzhin, V. S. Ryumshin +1
The peculiarities of phase states of the triplet boson model for orthonickelates are investigated analytically and by means of numerical simulations. The conditions of thermodynami…
The mean field approximation for a system of triplet bosons in nickelates
V. S. Ryumshin, S. V. Nuzhin, Yu. D. Panov +1
Rare-earth orthonickelates RNiO3 are Jahn-Teller magnets, unstable with respect to the anti-Jahn-Teller disproportionation reaction with the formation of a system equivalent to a s…
