Structural, dielectric and magnetic characteristics of Zr–Ni substitution on Barium X-type hexagonal ferrites synthesized through sol–gel autocombustion method

Gallium-substituted X-type hexagonal ferrites Sr2Co2GaxFe28−xO46: effect of substitution and heating temperature on phase formation and magnetic and dielectric properties

“…19 Other more recent studies on Sr 2 Ni 2 X ferrites have shown that lower temperatures of 1250 °C are required for pure phases. 20,21 Recent trends indicate research into composites being made for supercapacitor applications22 apart from the high frequency applications. 20…”

“…19 Other more recent studies on Sr 2 Ni 2 X ferrites have shown that lower temperatures of 1250 1C are required for pure phases. 20,21 Recent trends indicate research into composites being made for supercapacitor applications22 apart from the high frequency applications. 20 In the present work, we have probed the phase formation occurring in gallium-substituted Sr 2 Co 2 X hexagonal ferrites (Sr 2 Co 2 Ga x Fe 28Àx O 46 ) with different calcination temperatures.…”
