Field induced anisotropic cooperativity in a magnetic colloidal glass
E Wandersman, Y Chushkin, E Dubois +3
The translational dynamics in a repulsive colloidal glass-former is probed by time-resolved X-ray Photon Correlation Spectroscopy. In this dense dispersion of charge-stabilized and…
Bulk modulus of the nanoparticle system in concentrated magnetic fluids and local field-induced structural anisotropy
E. Wandersman, A. Cēbers, E. Dubois +3
In the present study we probe the bulk modulus and the structure of concentrated magnetic fluids by Small Angle X-ray Scattering. The electrostatically stabilized nanoparticles exp…
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…
