Crystalline and amorphous FeTi andFe2Ti

Amorphous FeTi, ${\mathrm{Fe}}_2$Ti, and their crystalline counterparts are compared by measurements of x-ray diffraction, conductivity, and ${}_{}{}^{57}{}_{}{}^{}\mathrm{Fe}$ Mössbauer spectroscopy. In FeTi one has the unique opportunity to compare a cubic crystal with its amorphous analog. X-ray diffraction and hyperfine interactions indicate no clear correlation between the crystalline and the amorphous states. The electrical conductivity exhibits distinctive behavior for the two states.
