Abstract: Ti-doped barium strontium hexaferrites (Ba0.8Sr0.2Fe12-xTixO19, x = 0.0–0.20) were synthesized via solid-state reaction to investigate Ti substitution effects on structural, optical, and magnetic properties... The x = 0.20 composition emerges as a promising candidate for magneto-optic devices.

Highlights

Bandgap decreases (2.21 to 1.89 eV) enhancing visible light absorption.
Optimal Mₛ (48.20 emu/g) & Hc (1094 Oe) at x = 0.20.
Lowest porosity (8.86%) improves domain alignment.
Critical Ti level (x = 0.10) marks lattice shift correlating with coercivity.
