Magnetic & Dielectric Hexagonal Ceramic Oxides of Ba0.8Zn0.2Fe12O19& Ba0.8Ti0.2Fe12O19Nano-Ceramic Oxide have been synthesized using Auto-Combustion synthesis approach reported for influence of Di & tetra Valant Substitution (Zn2+& Ti4+) on magnetic,optical, luminescence and dielectric response.Diffraction peak positioned at 2θ ~ 34.11 signature for crystallization of prepared Nano ceramic oxides in hexagonal crystal phase with space group P63/mmc No. 194 whereas microstructure reveals densification with least porosity and increased grain growth whereas crystallite size calculated using Debye Scherrer formula stamped for successful synthesis ofNano composites, respectively. S- shaped magnetic hysteresis loops with improved magnetic characteristic reveals direct influence of Zn2+& Ti4+substitution as compared to pure BaFe12O19 hexaferrite whereas low coercivity reveals soft ferrite nature (Temporary Magnet) suggesting that prepared solid solutions usefulness of in storage applications as well as for coils of transformers in electrical devices whereas square-ness ratio (Mr /Ms = >0.5 &< 1) shows multi-domain structure with presence of ferromagnetic ordering whereas change in value of magnetic moment (ƞB) reveals magnetic behavior resulted due to up & down spin of Fe3+ coupled at octahedral and tetrahedral sites. Shift in peak position in luminescent profile shows shifting in color emission whereas dielectric and conductivity spectroscopy shows that prepared Nano-Ceramic Oxide useful for Capacitive Applications
