Nanohexaferrites of BaV{sub x}Fe{sub 12−x}O{sub 19} (0.0 ≤ x ≤ 0.1) were prepared using sol–gel auto-combustion. The structure and morphology of BaV{sub x}Fe{sub 12−x}O{sub 19} (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 (M{sub s}), retentivity (M{sub r}), magneto-crystalline anisotropy fields (H{sub a}), and coercive field (H{sub c}) were enhanced for low V{sup 3+} contents and were maximum for BaV{sub 0.04}Fe{sub 11.96}O{sub 19} (x = 0.04) nanohexaferrites, showing the strengthening of magnetic properties.
