Spin glasses : experimental signatures and salient outcomes
Eric Vincent, Vincent Dupuis
Within the wide class of disordered materials, spin glasses occupy a special place because of their conceptually simple definition of randomly interacting spins. Their modelling ha…
Anisotropy-axis orientation effect on the magnetization of γ-Fe2O3 frozen ferrofluid
Sawako Nakamae, Caroline Thibierge, Katsuyoshi Komatsu +5
The effect of magnetic anisotropy-axis alignment on the superparamagnetic (SPM) and superspin glass (SSG) states in a frozen ferrofluid has been investigated. The ferrofluid studie…
Noise Measurement of Interacting Ferromagnetic Particles with High Resolution Hall Microprobes
K. Komatsu, D. L'Hote, S. Nakamae +7
We present our first experimental determination of the magnetic noise of a superspinglass made of < 1 pico-liter frozen ferrofluid. The measurements were performed with a local mag…
Spin glass behavior in an interacting gamma-Fe2O3 nanoparticle system
D. Parker, V. Dupuis, F. Ladieu +4
In this paper we investigate the superspin glass behavior of a concentrated assembly of interacting maghemite nanoparticles and compare it to that of canonical atomic spin glass sy…
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…
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…
