The Melting Behaviors of the Bimetallic Cluster Co_nCu_55-n(n=0~55)

Abstract:

The melting behaviors of Co_nCu_55-n(n=0~55) bimetallic cluster were studied by using semi-empirical Gupta potential combined with molecular dynamics simulations. The melting point of the Co_nCu_55-n(n=0~55) cluster shows itself the trend of going up, accompanied by the increasing of the Cobalt atomicity. However, it is between Co₅₅ and Cu₅₅ elementary cluster for melting point overall. Meanwhile the variation in the width of pre-melting temperature is greater, if around n0 or n55, but it is lesser nearly n55/2(namely Co and Cu at the same atomicity). In addition, the saturation point of specific heat capacity can be determined corresponding to the peak of Lindemann index.
