The Change of D-Electron Occupancy in TiNi and Ni3Ti Compounds Measured from the White-Line Intensity of Electron Energy Loss Spectroscopy

Abstract:

The electron energy loss spectroscopy (EELS) of pure Ti, TiNi, Ni3Ti and pure Ni has been acquired and d-electron occupancy of both Ti and Ni in the metals has been measured from the white-line intensity. It is found that the change of d-electron occupancy of Ni is very small in all metals, but the d-electron occupancy of Ti in Ni3Ti increases considerable large relative to pure Ti. The change of d-electron occupancy is discussed in terms of charge transfer mechanism, local charge neutrality (LCN) approximation, and hybridization.
