Exploration of crystal structure, magnetic and dielectric properties of titanium-barium hexaferrites

Popis výsledku v původním jazyce

The BaFe12-xTixO19 hexaferrites up to x = 3.00 were extended. XRD patterns were Rietveld fitted for P6(3)/mmc (no. 194) space group and the unit cell parameters were defined. The a parameter and V volume of unit cell change non-monotonically with x while the c parameter has linear behavior. The Ti4+ cations substitute the Fe3+ cations in the 2a, 4fVI and 12 k octahedral positions. This is confirmed by the Mossbauer spectroscopy. M-s spontaneous magnetization was determined with the law of approach to saturation from field magnetization at 5 K and 300 K. The epsilon(/) real part of the permittivity increases constantly with increasing temperature and decreases with frequency. The main objective of this study is an interpretation of the magnetic and dielectric properties of the titanium-barium hexaferrites which has performed in frame of breakdown of Fe3+ -O2- -Fe3+/2+(Ti4+) indirect superexchange interactions taking into account the positions occupation.
