Influence of Concentration Fluctuations on Relaxation Processes in Spin Glasses
Quantum Beam Science, 2018 Using the unique combination of atomically resolved atom probe tomography (APT) and volume averaged neutron (resonance) spin echo (NRSE and NSE) experiments, the influence of nano-scaled clusters on the spin relaxation in spin glasses was studied.

Large Exchange Bias Triggered by Transition Zone of Spin Glass
Advanced 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
AIP 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 ...

Chirality scenario of the spin-glass ordering [PDF]
J. Phys. Soc. Jpn. 79, 011007 (2010), 2009 Detailed account is given of the chirality scenario of experimental spin-glass transitions. In this scenario, the spin glass order of weakly anisotropic Heisenberg-like spin-glass magnets including canonical spin glasses are essentially chirality driven. Recent numerical and experimental results are discussed in conjunction with this scenario.

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

Phase Transitions between Different Spin-Glass Phases and between Different Chaoses in Quenched Random Chiral Systems [PDF]
Phys. Rev. E 96, 032103 (2017), 2017 The left-right chiral and ferromagnetic-antiferromagnetic double spin-glass clock model, with the crucially even number of states q=4 and in three dimensions d=3, has been studied by renormalization-group theory. We find, for the first time to our knowledge, four different spin-glass phases, including conventional, chiral, and quadrupolar spin-glass ...

Nature of the ordering of the three-dimensional XY spin glass [PDF]
Phys. Rev. Lett. 87, 187204 (2001), 2001 Spin and chirality orderings of a three-dimensional XY spin glass are studied by extensive Monte Carlo simulations. By calculating an appropriately defined spin-overlap distribution function, we show that the finite-temperature chiral-glass transition does not accompany the standard spin-glass order, giving support to the spin-chirality decoupling ...

Local inspection of magnetic properties in GdMnIn by measuring hyperfine interactions
AIP 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.

Spin-chirality decoupling in Heisenberg spin glasses and related systems [PDF]
J. Mag. Mag. Mater., 310, 1487 (2007), 2006 Recent studies on the spin and the chirality orderings of the three-dimensional Heisenberg spin glass and related systems are reviewed with particular emphasis on the possible spin-chirality decoupling phenomena. Chirality scenario of real spin-glass transition and its experimental consequence on the ordering of Heisenberg-like spin glasses are ...
