Abstract: 

The paper analyzes magnetic properties, crystal structure and EPR spectra of ZnO:Mn nanocrystals obtained by ultrasonic spray pyrolysis. It has been investigated influence of the type of carrier gas - air and nitrogen on the magnetic properties of the nanocrystals at room temperature. Also it has been investigated effect of heat treatment at T = 800°C and phase of Mn2O3 presented in the nanocrystals of ZnO:Mn, on the magnetic properties.

Keywords: 
magnetic properties, spray pyrolysis, EPR spectra, nanocrystals.
