NANOCOMPOSITE MAGNETIC POWDER MATERIALS OBTAINED BY MECHANOCHEMICAL SYNTHESIS

摘要

The composite materials showing concurrently dielectric and magnetic properties have now found their particular place in microelectronics aimed at developing proven memory and storage devices as well as to creating different transducers, modulators and electromagnetic spin and acoustic spin wave generators. Such materials are classified as segnetomagnetics. The reversibility of polarization in electromagnetic field; reversibility of magnetization in magnetic field; double optical refraction (natural and modulated) and absorption; dependence of resonance frequencies of spin waves on the applied magnetic field and stable operation within millimetric and IR bandwidth are the most important factors determining their applications.
