Abstract

The structure and thermodynamic properties of transitionmetal clusters containing N atoms are investigated for N=6 or 7 using molecular dynamics. The melting transition and phase diagram (energy-temperature curve) are studied. The “quasi-solid state” is found in the region of the temperature near and below the melting point, where clusters make structural transition from one isomer to others without topological change. The ate of transition is found to increase as temperature increases. This result is proposed as an interpretation for the structural instability of gold metal lusters observed experimentally by S.Iijima and T.Ichihashi Phys. Rev. Lett. 56, 616 (1986)).
