Josephson $S—F—I—S$ junctions are fabricated and investigated. In these junctions, the Ni$_{2}$MnGa ferromagnet with shape-memory effect is used as the $F$ layer. Possibility of fabrication of so-called $\pi$-junction is shown. Features of behaviour of the studied heterostructures are revealed. Magnetization of used nanoscale ferromagnetic thin film is calculated.

Key words: Josephson current, superconductivity, ferromagnetism, magnetic field, $\pi$-contact.
