Influence of Mn doping on structural, electrical and magnetic properties of (0.90)BiFeO3–(0.10)BaTiO3 composite

Structural, electrical and magnetic properties of chemically synthesized polycrystalline Mn doped (0.90)BiFeO 3 –(0.10)BaTiO 3 composites [(0.90)BiFe 1−x Mn x O 3 –(0.10)BaTiO 3 (x = 0.0, 0.03, 0.05 and 0.10)] were studied. The dielectric constant was observed to decrease when frequency was increase...

Beschreibung
Zusammenfassung:	Structural, electrical and magnetic properties of chemically synthesized polycrystalline Mn doped (0.90)BiFeO 3 –(0.10)BaTiO 3 composites [(0.90)BiFe 1−x Mn x O 3 –(0.10)BaTiO 3 (x = 0.0, 0.03, 0.05 and 0.10)] were studied. The dielectric constant was observed to decrease when frequency was increased from 20 Hz to 1 MHz and increased with the increase in temperature from 313 to 773 K. An interesting correlation between the antiferromagnetic Neel temperature (T N ) of bismuth ferrite and temperature dependent dielectric constant was observed. The calculated values of activation energies were in the order of 0.25–0.74 eV (
