Iron deficient BaNixMnxFe12−2xO19 (x = 0.0–0.5) hexagonal plates: single-domain magnetic structure and dielectric properties
The current investigation was carried out in order to present the structural, magnetic and dielectric properties of BaNi x Mn x Fe 12−2 x O 19 ( x = 0.0–0.5) (BNMFO) hexagonal microplates prepared via hydrothermal method followed by calcination at 950 °C for 5 h.
