Interrelation between magnetic and luminescent properties of aluminum oxide doped with copper and carbon

The correlation between concentration of structural defects (oxygen vacancies) and ferromagnetic behavior of nanopowders is presented. The correlation was established between dependencies of the ratio integral intensity of the yellow and the red bands of photoluminescence spectra (the ratio integral intensity of the green and the red bands of pulsed cathodoluminescence spectra) and magnetization from carbon doping level.
