Abstract

We have recently identified evidence of the Bose-Einstein condensation (BEC) of magnons in nanostructures. This behavior occurs for nanoparticles some 10s of nms in size (having some millions of atoms in a nanoparticle). Here we explore the effect of particle size on the BEC critical temperature and the blocking temperature. These considerations lead to our proposing a new phase diagram for magnetic behavior in nanoparticles, with distinct BEC, superparamagnetic, and ferromagnetic phases.
