摘要：

Mechanical activation and fine comminution of hexagonal oxide ferrimagnets by milling to a nanocrystalline state (ultradisperse powder), followed by sintering, leads to significant changes in the phase diagram, the temperature of synthesis, and the magnetic properties as compared to those of the materials obtained by traditional ceramic technology. The final material structure is formed through "chemical assembly"-sequential consolidation of nanodimensional particles (structure-forming blocks)-rather than through the formation of low-temperature phases and their decomposition with increasing temperature.
