Abstract
Among ferrites materials, M-type hexaferrites are very important due to their excellent technological applications. In the present investigation, Eu3+ and Co2+-doped Sr-hexaferrite at the sites of strontium and iron (Sr1-xEuxFe12-yCoyO19) were fabricated using normal micro-emulsion process. Magnetoplumbite single-phase material was approved with the help of X-ray diffraction analysis with crystallite sizes ranging from 35 to 57 nm. Magnetic characteristics like remanence (M-r), coercivity (H-c), and saturation magnetization (M-s) were estimated using hysteresis loop data. The concentration of Eu-Co increases the M-s and M-r values while reducing the value of H-c. To determine the DC electrical resistivity the method of two points probe was used which increases with the Eu-Co content. The reduction in values of coercivity, dielectric constant, and loss while enhancement in M-s, M-r, and resistivity against Eu-Co content, indicating that these materials are acceptable for commercial application in microwave appliances and recording media.
