Abstract
We present the first triple-axis neutron scattering measurements of magnetic fluctuations in nanoparticles using an antiferromagnetic reflection. Both the superparamagnetic relaxation and precession modes in similar to 15 nm hematite particles are: observed. The results have been consistently analyzed on the basis of a simple model with uniaxial anisotropy and the Neel-Brown theory for the relaxation.
