Abstract

A two-dimensional electron gas based quantum well Hall sensor is employed to measure the magnetic noise exhibited by a frozen ferrofluid made of maghemite nanoparticles. The dependence of the superspin glass transition of the system is also analyzed.

Abstract

Several homogeneously dispersed gamma-Fe2O3 nanoparticle assemblies of varying volume fraction regarding superspin glasses are studied. In a concentrated sample, the main features of atomic spin glasses are observed including aging phenomena for which a rescaling is proposed.
