Abstract

When the size of bimetallic alloys decreases to nanometer scale, the electronic, magnetic, optic, catalytic, biomedical and thermodynamic properties are different substantially from their bulk properties. In this work, a nanothermodynamics model was established to investigate the size-dependent Curie temperature Tc and order-disorder transition temperature T 0 of nano-sized binary alloys. It is found that both Tc and T0 decrease with decreasing material size and the model predictions are consistent with experimental data. This provides new insights into the fundamental understanding of the physicochemical properties in magnetic nanoalloys and also their potential applications as magnetic-storage media.
