摘要：

In the present paper magnetic and elastic properties of the Ni+SrFe12O19 nanocomposites were examined in detail. Samples were in two forms: i) mechanically pressed cylindrical pellets and ii) filled polymer (amine-epoxy resin) coating on aluminum substrate. The so called apparent Young's modulus was determined by measurements of the free flexural vibrations frequency by means of vibrating reed technique. Magnetic research was carried out using VSM magnetometer. It was shown that replacement of SrFe12O19 with nano Ni powder results in an increase in material resistivity to elastic deformation. The influence of size reduction of SrFe12O19 powder particles on magnetic parameters of the studied nanocomposites were discussed in detail.
