Spin-phonon coupling in uniaxial anisotropic spin-glass based on Fe2TiO5 pseudobrookite
(2019-08-30)
The ferric pseudobrookite is a rare example of uniaxial anisotropic spin-glass insulator, depicting a multiglass behavior and magnetoelectric coupling. Here, we present Raman spectroscopy results in order to elucidate the ...
Spin-phonon induced magnetic order in the kagome ice
(American Physical Society, 2013-06)
We study the effects of lattice deformations on the kagome spin ice, with Ising spins coupled by nearest-neighbor exchange and long-range dipolar interactions, in the presence of in-plane magnetic fields. We describe the ...
Effect of phonons on the electron spin resonance absorption spectrum
(IOP Publishing Ltd., 2020-07)
The unavoidable presence of vibrations in solid-state devices can drastically modify the expected electron spin resonance (ESR) absorption spectrum in magnetically active systems. In this work, we model the effect of phonons ...
Sistemas antiferromagneticos unidimensionais de spin-1
(Universidade Federal de Minas GeraisUFMG, 2007-08-31)
Attending to the current tendency of research in quantum magnetism,our object of study comprises one-dimensional spin-1 antiferromagnetic(AFM) systems. They are analysed for two different physical pictures: anoise-driven ...

Nonmonotonic spin relaxation and decoherence in graphene quantum dots with spin-orbit interactions
(American Physical Society - APSCollege Park, 2014-03)
We investigate the spin relaxation and decoherence in a single-electron graphene quantum dot with Rashba and intrinsic spin-orbit interactions.We derive an effective spin-phonon Hamiltonian via the Schrieffer-Wolff ...
