Photoluminescence Properties

It has been demonstrated that the slow relaxation of magnetization can be achieved in high spin tetrahedral CoII centres with an easy-plane magnetic anisotropy within the double-stranded helicates. The photoluminescence properties of the Zn analogues were studied in different solvents.

Magnetic force microscopy and magnetometry were used to study the magnetic characteristics of pressed nanosized powders BaFe12O19. The powders were obtained by chemical coprecipitation. Magnetic anisotropy of the “easy-plane” type, formed after the pressing operation, was found. The nature of the appearance of anisotropy is discussed.
