Large Exchange Bias Triggered by Transition Zone of Spin Glass

open access: yesAdvanced Physics Research, 2023
Exchange bias has increasingly practical significance in magnetoresistive and spintronic devices. However, the underlying mechanism of exchange bias in bulk compounds with the structural single‐phase and inhomogeneous magnetic phases is still elusive ...

Study of canonical spin glass behavior in Co doped LaMnO3

open access: yesAIP Advances, 2021
Temperature-dependent magnetic and a.c. susceptibility measurements were done on single phase polycrystalline LaMn1-yCoyO3 (y = 0.1, 0.4) samples. The field cooled and zero field cooled magnetic measurements performed indicate the presence of spin glass ...

Universal spin-glass behaviour in bulk LaNiO2, PrNiO2 and NdNiO2

open access: yesNew Journal of Physics, 2022
Motivated by the recent discovery of superconductivity in infinite-layer nickelate thin films, we report on a synthesis and magnetization study on bulk samples of the parent compounds R NiO _2 ( R = La, Pr, Nd).

Spectral form factor of a quantum spin glass

open access: yesJournal of High Energy Physics, 2022
It is widely expected that systems which fully thermalize are chaotic in the sense of exhibiting random-matrix statistics of their energy level spacings, whereas integrable systems exhibit Poissonian statistics.

Finite-size critical scaling in Ising spin glasses in the mean-field regime [PDF]

open access: yes, 2016
We study in Ising spin glasses the finite-size effects near the spin-glass transition in zero field and at the de Almeida-Thouless transition in a field by Monte Carlo methods and by analytical approximations.

Local inspection of magnetic properties in GdMnIn by measuring hyperfine interactions

open access: yesAIP Advances, 2021
GdMnIn is reported to crystallize in the hexagonal MgNi2-type structure presenting a spin-glass behavior with no magnetic order attributed to the triangular spin frustration of magnetic ions.

Mn-induced multiple magnetic ground states in Sr_{3}(Ru_{1−x}Mn_{x})_{2}O_{7}

open access: yesPhysical Review Research, 2021
Transition-metal oxides provide an excellent platform to generate ground states by tuning the various degrees of freedom via stimuli such as chemical doping.

Coercivity and Exchange Bias in Ti-Doped Maghemite Nanoparticles

open access: yesMagnetochemistry, 2022
Ti-doped maghemite nanoparticles of average crystallite size 12.9 nm were synthesized using the sol–gel method. The XRD profile mainly showed the presence of maghemite phase with very small phases of TiO2 (rutile and anatase).
