The current investigation was carried out in order to present the structural, magnetic and dielectric properties of BaNixMnxFe12−2xO19 (x = 0.0–0.5) (BNMFO) hexagonal microplates prepared via hydrothermal method followed by calcination at 950 °C for 5 h. The X-ray diffraction patterns of x = 0.0–0.5 contents confirmed the formation of hexagonal phases. The morphology and grain size of the BNMFO was examined by the field emission of scanning electron microscope. The results indicated that the BNMFO exhibited the hexagonal platelet like grains of size ranging from 2.4 to 3.5 µm. Two peaks were formed in the Fourier transform infrared spectra at 585 and 427 cm−1 and indicated the formation of metal–oxygen bonds. It was observed that the band gap was decreased with the increase in ‘x’. From the room temperature M–H curves, it was observed that the high saturation magnetization (45.8–53.9 emu/g) was recorded for all samples. Further, the coercive field was decreased from 3133 to 1098 Oe as a function of ‘x’. The real and imaginary parts of dielectric permittivity parameters were found to be increased with the increase in ‘x’.
