Synthesized M-type Ba0.4Pb0.6Fe12-xCoxO19 (x = 0.00 to 0.40) hexaferrites using citrate gel auto-combustion revealed M-phase, PbM, and hematite in XRD analysis, showcasing their structural diversity.
Magnetic analyses displayed hard behavior, notably x = 0.10 composition exhibiting the highest saturation magnetization (55.427 A m2/kg) and coercivity range (0.058 T to 0.390 T), emphasizing their magnetic potential.
Cobalt substitutions significantly influenced dielectric properties, with ac conductivity increasing up to x = 0.10 and decreasing thereafter, mirrored by similar trends in the dielectric constant, indicating nuanced electrical control.
XRD confirmed M-phase formation alongside PbM and hematite, revealing slight unit cell volume increments linked to cobalt's larger ionic radii, impacting the structural attributes of these hexaferrites.
