Real spin glasses relax slowly in the shade of hierarchical trees
Eric Vincent, J. Hammann, Miguel Ocio
The Parisi solution of the mean-field spin glass has been widely accepted and celebrated. Its marginal stability in 3d and its complexity however raised the question of its relevan…
The effect of cooling rate on aging in spin glasses
Dinah Parker, Francois Ladieu, Jacques Hammann +1
Aging is a well known property of spin glass materials and has been investigated extensively in recent years. This aging effect is commonly observed by thermal remnant magnetizatio…
Aging, rejuvenation and memory phenomena in spin glasses
V. Dupuis, F. Bert, J. -P. Bouchaud +4
In this paper, we review several important features of the out-of-equilibrium dynamics of spin glasses. Starting with the simplest experiments, we discuss the scaling laws used to…
The relative influences of disorder and of frustration on the glassy dynamics in magnetic systems
F. Ladieu, F. Bert, V. Dupuis +2
The magnetisation relaxations of three different types of geometrically frustrated magnetic systems have been studied with the same experimental procedures as previously used in sp…
Spin Anisotropy and Slow Dynamics in Spin Glasses
F. Bert, V. Dupuis, E. Vincent +2
We report on an extensive study of the influence of spin anisotropy on spin glass aging dynamics. New temperature cycle experiments allow us to compare quantitatively the memory ef…
Aging, rejuvenation and memory effects in re-entrant ferromagnets
V. Dupuis, E. Vincent, M. Alba +1
We have studied the slow dynamics of the ferromagnetic phases of the re-entrant CdCr_{2x}In_{2-2x}S_4 system for 0.85<x<=1 by means of low frequency ac susceptibility and magnetiza…
A Role of Initial Conditions in Spin-Glass Aging Experiments
V. S. Zotev, G. F. Rodriguez, R. Orbach +2
Effect of initial conditions on aging properties of the spin-glass state is studied for a single crystal Cu:Mn 1.5 at %. It is shown that memory of the initial state, created by th…
Aging and memory properties of topologically frustrated magnets
V. Dupuis, E. Vincent, J. Hammann +2
The model 2d kagome system (H3O)Fe3(SO4)2(OH)6 and the 3d pyrochlore Y2Mo2O7 are two well characterized examples of low-disordered frustrated antiferromagnets which rather then con…
Aging, rejuvenation and memory effects in Ising and Heisenberg spin glasses
V. Dupuis, E. Vincent, J. -P. Bouchaud +3
We have compared aging phenomena in the Fe_{0.5}Mn_{0.5}TiO_3 Ising spin glass and in the CdCr_{1.7}In_{0.3}S_4 Heisenberg-like spin glass by means of low-frequency ac susceptibili…
Finite Size Effects on Spin Glass Dynamics
Y. G. Joh, R. Orbach, G. G. Wood +2
The recent identification of a time and temperature dependent spin glass correlation length, , has consequences for samples of finite size. Qualitative arguments are gi…
Aging in a topological spin glass
A. S. Wills, V. Dupuis, E. Vincent +2
We have examined the nonconventional spin glass phase of the 2-dimensional kagome antiferromagnet (H_3 O) Fe_3 (SO_4)_2 (OH)_6 by means of ac and dc magnetic measurements. The freq…
Aging phenomena in spin glass and ferromagnetic phases: domain growth and wall dynamics
E. Vincent, V. Dupuis, M. Alba +2
We compare aging in a disordered ferromagnet and in a spin glass, by studying the different phases of a reentrant system. We have measured the relaxation of the low-frequency ac su…
Memory interference effects in spin glasses
K. Jonason, P. Nordblad, E. Vincent +2
When a spin glass is cooled down, a memory of the cooling process is imprinted in the spin structure. This memory can be disclosed in a continuous heating measurement of the ac-sus…
Extraction of the Spin Glass Correlation Length
Y. G. Joh, R. Orbach, G. G. Wood +2
The peak of the spin glass relaxation rate, S(t)=d{-M_{TRM}(t,t_w)}/H/{d ln t}, is directly related to the typical value of the free energy barrier which can be explored over exper…
Memory and Chaos Effects in Spin Glasses
K. Jonason, E. Vincent, J. Hammann +2
New low frequency ac susceptibility measurements on two different spin glasses show that cooling/heating the sample at a constant rate yields an essentially reversible (but rate de…
