Experimental Evidence of Fluctuation-Dissipation Theorem Violation in a Superspin Glass
Katsuyoshi Komatsu, D. L'Hote, Sawako Nakamae +5
We present the experimental observation of the fluctuation-dissipation theorem (FDT) violation in an assembly of interacting magnetic nanoparticles in the low temperature superspin…
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…
Superspin glass aging behavior in textured and nontextured frozen ferrofluid
Sawako Nakamae, Emmanuelle Dubois, Vincent Dupuis +4
The effect of magnetic anisotropy-axis alignment of individual nanoparticles on the collective aging behavior in the superspin glass state of a frozen ferrofluid has been investiga…
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…
