X-Ray analysis showed that in the as-deposited Bi films is formed a mixture of rhombohedral and cubic nanocrystalline Bi phases and traces of Bi2O3 oxide. Heat treatment at 650 K leads to the decay of the Bi non-equilibrium phase. In the Mo original films is formed a mixture of Mo cubic phase and MoO2, MoO3 oxides. As a result of heat treatment at the temperature of about 870 K phase composition and the grain size remains unchanged. FeBiMo films in the initial state is a mixture of rhombohedral and cubic Bi phases and the hexagonal Fe phase. In the Mo-doped films non-equilibrium Bi phase remains after heat treatment at 770 K. Construction of the temperature dependence of resistivity has revealed the reversible phase transition in the Bi films. A similar behavior of Bi properties is also manifested in FeBiMo films. The analysis of demagnetization curves of Bi films showed a manifestation of hysteresis properties, which is not typical for diamagnetic. This can be explained by the Bi2O3 phase presence.
