Annotation In the article, the structure, phase composition and magnetoresistive properties of single- and three-layer films based on Fe and Ge were studied. It is established that in such films eutectic is formed based on diluted solid solutions of Ge atoms in -Fe layers and of Fe atoms in -Ge layers at the total concentration of Ge atoms from 3 to 20 at.% in the temperature range of 300-870 K. It is shown that magnetoresistive properties of the films with eutectic composition are not significantly different from the properties of -Fe films.
