Abstract
The techniques of x-ray and ultra-violet photoemission spectroscopies have been used to investigate the electronic structures in Fe-30%Ni and Fe-27.5%Ni alloys in both the bcc and fcc phases. The similarities between the Fe 3s core level spectra, and between the XPS and UPS EDC's of the valence band, from the bcc and fcc phases of the Fe-Ni alloys, provide evidence that the Fe local magnetic moment persists in the fcc phase, and is about the same magnitude as in the bcc phase. The binding-energies of the Fe-2p1/2 and Fe-2p3/2 core levels of Fe-30%Ni and Fe-27.5%Ni are shifted from the values in pure Fe by + 0.40eV +- 0.05eV. The binding-energy of the Fe-3p core level of Fe-30%Ni is shifted from the value in pure Fe by + 0.40eV +- 0.05eV. The intensity of the Ni-3p core level in XPS spectra is considerably decreased when Fe-30%Ni has undergone the martensitic phase transition. The EDC's of the valence bands of Fe-30%Ni, Fe-27.5%Ni (in both the bcc and fcc phases) and pure Fe agree with published data.
