Investigation of Microstructural and Magnetic Properties of BaVxFe12-xO19 Nanohexaferrites

Abstract
Nanohexaferrites of BaVxFe12−xO19 (0.0 ≤ x ≤ 0.1) were prepared using sol–gel auto-combustion. The structure and morphology of BaVxFe12−xO19 (0.0 ≤ x ≤ 0.1) nano-sized hexaferrites were explored by X-ray diffraction (XRD), scanning electron microscopy (SEM) coupled with EDXS. XRD analysis indicated particle size in the 55–60-nm interval. SEM and EDXS investigations confirmed the formation of the desired composition of V-substituted Ba-hexaferrites. The magnetic properties of products were studied. The magnetic M(H) hysteresis loops revealed that all produced nanohexaferrites display ferromagnetic-like comportment. The deduced saturation magnetization (Ms), retentivity (Mr), magneto-crystalline anisotropy fields (Ha), and coercive field (Hc) were enhanced for low V3+ contents and were maximum for BaV0.04Fe11.96O19 (x = 0.04) nanohexaferrites, showing the strengthening of magnetic properties.
