Sažetak
In the research of multifunctional properties, one of the most important targets is a thorough understanding of a correlation between structural features of material and desired physical and chemical properties. High thermal stability makes BaAl2O4 suitable for fabrication of fluorescent lamps, LEDs, FEDs, etc. – this especially refers to doped BaAl2O4 due to optimal combination of microstructural, electrical, and optical parameters [1]. Physical properties of BaAl2O4 host can be controlled by modification of crystal structure and electronic state by partial substitution of Al and Ba sites cations and/or thermal treatment under reduction conditions [2]. The influence of Co2+ on the BaAl2O4 lattice and its magnetic properties was explored using the PXRD, Uv-Vis and magnetic studies. Magnetization measurements of BaAl2O4 doped with 4, 8 and 12 at. % Co in form of pressed pellets were performed using SQUID magnetometer at temperatures 2 - 400 K and fields up to 5 T. We found that by increasing the amount of Co, resulting magnetization also increases in otherwise non-magnetic BaAl2O4 material. In order to describe magnetic behaviour, it was necessary to include magnetic anisotropy of paramagnetic Co2+ ions. Since BaAl2O4 is ferroelectric [3], very motivating is similar work where Fe doping of ferroelectric BaTiO3 produced also the magnetic response of material [4]. If considerable magnetic response could be obtained, it could lead to the novel magnetoelectric and/or multiferroic state in doped BaAl2O4.
