Аннотация: In the last few years an interest in field of quantum dots devices creating has been increased. In this work the nanocrystallite with Frank-Kasper structure was examined as the quantum dot in amorphous film. An ability to create all-inorganic Quantum Dots Light Emission Device may be considered for Tb(30)Fe(70), Co(80)C(20) and Co(50)Pd(50) films. The self-organisation of atomic structure in Tb(30)Fe(70), Co(80)C(20) and Co(50)Pd(50) films, which possess large values of perpendicular magnetic anisotropy (PMA) constant (K(perpendicular to)similar to 10(6) erg/cm(3)), were investigated by methods of electron diffraction and transmission electron microscopy, including the method of bend contours([1]). The crystallization of the films proceeds in an explosive way forming different dissipative structures from initial nanocrystalline state. In previous works([2,3]) it was shown that after crystallization (T(ann)similar to 260-330 degrees C) the atomic structures of Tb(30)Fe(70) Co(80)C(20) and Co(50)Pd(50) films are tetrahedrally close-packed Frank-Kasper structures. In this work the structural model of thin film at mezoscale and its correlation with magnetic and optical properties is proposed.
