Summary, in English

In this work we demonstrate that it is possible to create new magnetic material based on metal-containing nanoparticles stabilized on the surface of polytetrafluoroethylene nanogranules. Magnetic properties of these materials have been investigated. The materials were prepared by a method of thermal decomposition of metal-containing compounds in the heated polytetrafluoroethylene-oil system. Transmission electron microscopy data show that the particles diameter is 4-6 nm. Magnetic studies show that for the obtained nanoparticles blocking temperature and the magnetic constant anisotropy is higher than for bulk materials. That fact makes it promising material for the magnetic recording applications.
