Magnetovolume instabilities in the pressure dependence of the K-edge circular dichroism of Fe3C Invar particles

E. Duman, M. Acet, E. F. Wassermann +4

The p-electrons of carbon in the interstitial compound Fe3C hybridize with the Fe d-band and enhance the valence electron concentration of Fe from 8 to 8.67. At this concentration,…
