Spin-glass dynamics in the presence of a magnetic field: exploration of microscopic properties 2021 Access copy available to the general public Unrestricted The synergy between experiment, theory, and simulations enables a microscopic analysis of spin-glass dynamics in a magnetic field in the vicinity of and below the spin-glass transition temperature T g. The spin-glass correlation length, ¿(t, t w; T), is analysed both in experiments and in simulations in terms of the waiting time t w after the spin glass has been cooled down to a stabilised measuring temperature T < T g and of the time t after the magnetic field is changed. This correlation length is extracted experimentally for a CuMn 6 at. % single crystal, as well as for simulations on the Janus II special-purpose supercomputer, the latter with time and length scales comparable to experiment. The non-linear magnetic susceptibility is reported from experiment and simulations, using ¿(t, t w; T) as the scaling variable. Previous experiments are reanalysed, and disagreements about the nature of the Zeeman energy are resolved. The growth of the spin-glass magnetisation in zero-field magnetisation experiments, M ZFC(t, t w; T), is measured from simulations, verifying the scaling relationships in the dynamical or non-equilibrium regime. Our preliminary search for the de Almeida-Thouless line in D = 3 is discussed. info:eu-repo/grantAgreement/EC/H2020/694925/EU/Low Temperature Glassy Systems/LoTGlasSy This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 694925-LoTGlasSy info:eu-repo/grantAgreement/ES/MCIU/FPU18/02665 info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/PGC2018-094684-B-C21 info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/PGC2018-094684-B-C22 info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/PID2019-103939RB-I00 info:eu-repo/grantAgreement/ES/MINECO/FIS2016-76359-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.234 2021 PHYSICS, MATHEMATICAL 15 / 56 = 0.268 2021 Q2 T1 MECHANICS 86 / 138 = 0.623 2021 Q3 T2 0.429 2021 Statistics and Probability 2021 Q3 Statistical and Nonlinear Physics 2021 Q3 3.9 2021 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion Zhai, Q.
