摘要：

Ce-Co substituted, barium hexaferrite with the chemical composition of Ba0.5Ce0.5Fe11CoO19 was prepared by using the ceramic technique. The structural properties of the Ce-Co substituted, barium hexaferrite was investigated using X-ray diffractometer. The magnetic hysteresis loop of the sample was characterized by vibrating sample magnetometry. In order to identify the surface morphology of the sample, field emission scanning electron microscopy was used. Using the transmission/reflection coaxial line method in the range of 2-18GHz, the complex permeability and complex permittivity, the reflection loss (RL) properties, absorption loss and shielding effectiveness of the prepared composition were determined. The maximum RL value of -31.4dB at 11.4GHz with a 3mm thickness sample was obtained and the maximum shielding effectiveness value was observed around 59.2dB.
