| Abstract: | The optical and X-ray photoelectronic spectra and temperature dependence of magnetic susceptibility are investigated. It is found that at martensitic transformation in TiNi electron redistribution occurs which is accompanied by cardinal change of Fermi surface. Based on the data obtained in B2-structure (CsCl) EF is assumed to lie in the kT-vicinity of the N(E) peak that determines the tendency to the structural instability of B2. |
