Spin glass behavior and magnetic boson peak in a structural glass of a magnetic ionic liquid

open access: yesScientific Reports, 2021
Glassy magnetic behavior has been observed in a wide range of crystalline magnetic materials called spin glass. Here, we report spin glass behavior in a structural glass of a magnetic ionic liquid, C4mimFeCl4.

Delocalization transition in low energy excitation modes of vector spin glasses

open access: yesSciPost Physics, 2022
We study the energy minima of the fully-connected $m$-components vector spin glass model at zero temperature in an external magnetic field for $m\ge 3$.

Driven and Non-Driven Surface Chaos in Spin-Glass Sponges [PDF]

open access: yesChaos, Solitons and Fractals 176, 114159 (2023), 2023
A spin-glass system with a smooth or fractal outer surface is studied by renormalization-group theory, in bulk spatial dimension d=3. Independently varying the surface and bulk random-interaction strengths, phase diagrams are calculated. The smooth surface does not have spin-glass ordering in the absence of bulk spin-glass ordering and always has spin ...

Experimental setup to fabricate Rb–Xe gas cells for atom spin gyroscopes

open access: yesAIP Advances, 2022
An experimental setup to fabricate atomic vapor cells for atom spin gyroscope application, containing 87Rb, 129Xe, 131Xe, N2, and H2, is described. The setup comprises a high-vacuum chamber, an 87Rb ampule, a glass cell, gas lines, and a turbopump. First,

Eminuscent phase in frustrated magnets: a challenge to quantum spin liquids

open access: yesNature Communications, 2022
A spin-glass forms in frustrated magnetic systems when at low temperatures impurity sites “freeze” into a random spin configuration. Here, by looking back at previous experimental results, Syzranov and Ramirez show that the glass-transition temperature ...

A New Look at the Spin Glass Problem from a Deep Learning Perspective

open access: yesEntropy, 2022
Spin glass is the simplest disordered system that preserves the full range of complex collective behavior of interacting frustrating elements. In the paper, we propose a novel approach for calculating the values of thermodynamic averages of the ...

Asymmetric Phase Diagrams, Algebraically Ordered BKT Phase, and Peninsular Potts Flow Structure in Long-Range Spin Glasses [PDF]

open access: yesPhys. Rev. E105, 024122 (2022), 2021
The Ising spin-glass model on the three-dimensional (d=3) hierarchical lattice with long-range ferromagnetic or spin-glass interactions is studied by the exact renormalization-group solution of the hierarchical lattice. The chaotic characteristics of the spin-glass phases are extracted in the form of our calculated, in this case continuously varying ...

Short-term memory capacity analysis of Lu3Fe4Co0.5Si0.5O12-based spin cluster glass towards reservoir computing

open access: yesScientific Reports, 2023
Reservoir computing is a brain heuristic computing paradigm that can complete training at a high speed. The learning performance of a reservoir computing system relies on its nonlinearity and short-term memory ability.

Frustration-Induced Relaxation in Polycrystalline Nd1- xSrxCoO3 (x=0.10, 0.15, 0.20)

open access: yesChemical Engineering Transactions, 2018
This paper attempts to examine the details on the magnetic relaxation and aging effect of cobaltite Nd1- xSrxCoO3 (x=0.10, 0.15, 0.20). To this end, a series of polycrystalline Nd1-xSrxCoO3 samples were prepared in the traditional way, and their ...
