| Abstract: | This paper presents the synthesis and realization of the C-axis textured M-type barium ferrite BaScxFe12−xO19 (x = 0.1, 0.3, 0.6, 0.8, 1.0) using the solid-state method. Among this samples, the BaScxFe12−xO19 with x = 0.1 ferrite exhibits preferable magnetic properties with the saturation magnetization of ~ 4700 Gauss and squareness ratio of 0.65, which is suited for the realization of self-biased circulator design. Results of the SEM reveal that the Sc3+ has negligible effect on the crystal morphology. The measured results for the vibrating sample magnetometer indicate that increasing x of the induced Sc3+ yields decreasing the magneto-crystalline anisotropy field, saturation magnetization, coercivity, and reduces the squareness ratio. Besides, influence of Sc3+ on dielectric constant also have be investigated. [ABSTRACT FROM AUTHOR] |
