Summary

Magnetic noise of a frozen ferrofluid made of maghemite nanoparticles dispersed in glycerin is measured using a two-dimensional electron gas based quantum well Hall sensor. The frozen ferrofluid shows a superspin glass transition at 67 K. Below this temperature, the relation between the imaginary part of the ac susceptibility and the magnetic noise indicates a violation of the fluctuation-dissipation theorem. The measurement is done using a high-resolution quantum well Hall sensor with a spinning current technique, achieving a sensitivity of 2 mG/√Hz at 0.01 Hz and temperatures ranging from 20 to 85 K. The ferrofluid is made of 8.6 nm maghemite nanoparticles with a magnetic moment of 10^4 mB, dispersed in glycerin with a volume fraction of 15%. The superspin glass transition is observed at 67 K, and the magnetic noise is measured below this temperature, showing a deviation from the fluctuation-dissipation theorem.
