A Phase Diagram for the Bose-Einstein Condensation of Magnons

January 1, 2002
Author(s)
Lawrence H. Bennett, Edward Della Torre, Philip Johnson, R E. Watson
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
