The solid-to-liquid transition region of an Ag-Pd bimetallic nanocluster

The solid-liquid transition region of an Ag-Pd bimetallic cluster composed of 201 Ag and 201 Pd atoms is investigated by means of molecular dynamics simulation. An effective and convenient method is reported for finding that region. For external energy, Ag and Pd clusters were caused to collide with various initial velocities under the condition of a microcanonical ensemble. The Ag201-Pd201 bimetallic cluster was observed to completely melt at 900 K with a solid-liquid coexistence range of 50 K.
