Spin-Glass Behavior, Magnetic, and IR Spectroscopy Analysis of Multimetallic Compound Ni0.25Mn1.25[Fe(CN)6]·6.1H2O

open access: yesJournal of Spectroscopy, 2015
Multimetallic Prussian blue compound Ni0.25Mn1.25[Fe(CN)6]·6.1H2O has been prepared by coprecipitation. The temperature-dependent magnetic susceptibilities show the magnet transition for the compound at 8.5 K.

Large magnetocaloric effects in magnetic intermetallics: First-principles and Monte Carlo studies

open access: yesMATEC Web of Conferences, 2015
We have performed ab initio electronic structure calculations and Monte Carlo simulations of frustrated ferroic materials where complex magnetic configurations and chemical disorder lead to rich phase diagrams.

The Crisanti-Sommers Formula for Spherical Spin Glasses with Vector Spins [PDF]

open access: yesarXiv, 2019
We obtain the analogue of the Crisanti-Sommers variational formula for spherical spin glasses with vector spins. This formula is derived from the discrete Parisi variational formula for the limit of the free energy of constrained copies of spherical spin glasses. In vector spin models, the variations of the functional order parameters must preserve the

Replica Fourier Transform: Properties and applications

open access: yesNuclear Physics B, 2015
The Replica Fourier Transform is the generalization of the discrete Fourier Transform to quantities defined on an ultrametric tree. It finds use in conjunction of the replica method used to study thermodynamics properties of disordered systems such as ...

Nearest-neighbors neural network architecture for efficient sampling of statistical physics models

open access: yesMachine Learning: Science and Technology
The task of sampling efficiently the Gibbs–Boltzmann distribution of disordered systems is important both for the theoretical understanding of these models and for the solution of practical optimization problems.

Gibbs states of lattice spin systems with unbounded disorder

open access: yesCondensed Matter Physics, 2010
The Gibbs states of a spin system on the lattice Zd with pair interactions Jxyσ(x) σ(y) are studied. Here ∈ E, i.e. x and y are neighbors in Zd. The intensities Jxy and the spins σ(x), σ(y) are arbitrarily real.
