Cosingle bondTi substituted M-type barium hexaferrite BaFe12-2xCoxTixO19 (0.0 ≤ x ≤ 1.0) thick films were prepared by screen printing method. X-ray diffraction analysis confirmed the formation of single phase BaFe12O19 (BaM). The preferential site occupation of Co2+ and Ti4+ ion for Fe3+ ion at five different crystallographic sites (12k, 4f1, 4f2, 2a, and 2b) was measured by Mössbauer spectroscopy. The analyses showed Cosingle bondTi ions preferentially occupy 2b and 4f2 sites which were responsible for drastic decrease in magnetocrystalline anisotropy field (Ha). Magnetization (M) value found to be higher for x = 0.5. The coercivity (Hc) dropped dramatically, recording a reduction of about 95% at x = 1.0, attributed to decreased in Ha. SEM micrographs of Cosingle bondTi substituted films revealed hexagonal grain structure. The magnetic properties of Cosingle bondTi substituted BaM, suggests a possible candidate for microwave applications.
