FePt nanoparticles protected by poly(N-vinyl-2-pyrrolidone) (PVP) as a protective agent are synthesized by a chemical route. Diameter dependence of coercivity at low temperatures below $20 K for the FePt nanoparticles synthesized at various reaction temperatures exhibits an anomalous magnetic behavi
