The role of non-collinear spins on the magnetic properties of uncoupled nanometer-size particles
Source abstract
Abstract
Abstract A study of the magnetic properties of an assembly of non-interacting iron oxide-based nano-particles is presented. The measured average particle size is found to approach the expected thickness of the spin disordered layer. In this regime, the magnetization is characterized by two parameters: T b above which the particle acts as a single domain, and T E below which intra-particle coupling between pinned and unpinned spins become important.

17. The structure and stoichiometry of our nano-particulate sample departs markedly from those of a typical Co-ferite. A rough estimate of particle size, d, in terms of spinel lattice constants (l.c.≳8Å), yields d≲2 l.c., which raises the question of phase stability at this scale. Consequently, the description of the magnetic properties of our samples in terms of surface spin disorder, as in the case of structurally and compositionally well defined Co-ferites, is not applicable.
