Nontrivial phase diagram for an elastic interaction model of spin crossover materials with antiferromagnetic-like short-range interactions
Masamichi Nishino, Seiji Miyashita, Per Arne Rikvold
We study the phase diagram of an elastic interaction model for spin crossover (SC) materials with antiferromagnetic-like short-range interactions. In this model, the interplay betw…
Fluctuations in a model ferromagnetic film driven by a slowly oscillating field with a constant bias
Gloria M. Buendia, Per Arne Rikvold
We present a numerical and theoretical study that supports and explains recent experimental results on anomalous magnetization fluctuations of a uniaxial ferromagnetic film in its…
Phase diagrams and free-energy landscapes for model spin-crossover materials with antiferromagnetic-like nearest-neighbor and ferromagnetic-like long-range interactions
Chor-Hoi Chan, Gregory Brown, Per Arne Rikvold
We present phase diagrams, free-energy landscapes, and order-parameter distributions for a model spin-crossover material with a two-step transition between the high-spin and low-sp…
Density of states for systems with multiple order parameters: a constrained Wang-Landau method
Chor-Hoi Chan, Gregory Brown, Per Arne Rikvold
A macroscopically constrained Wang-Landau Monte Carlo method was recently proposed to calculate the joint density of states (DOS) for systems with multiple order parameters. Here w…
Macroscopically constrained Wang-Landau method for systems with multiple order parameters and its application to drawing complex phase diagrams
Chor-Hoi Chan, Gregory Brown, Per Arne Rikvold
A generalized approach to Wang-Landau simulations, macroscopically constrained Wang-Landau, is proposed to simulate the density of states of a system with multiple macroscopic orde…
