Single-phase Z-type strontium cobalt hexaferrite was prepared by polymerizable complex method. Magnetic properties and dynamic magnetic response for high frequency of the Z-type ferrite were studied. Single-phase Z-type hexaferrite was obtained by heating at 1473K for 5 hours in air. Phase identification and determination of lattice parameters were carried out by powder X-ray diffraction (XRD). Magnetic properties were discussed by measuring of M-H curve with vibrating sample magnetometer (VSM). The complex permeability and permittivity over 0.2-18GHz were measured using a vector network analyzer with transmission-reflection-line (TRL) calibration. The results show that the single-phase Z-type strontium cobalt hexaferrite prepared in this study is one of potential candidates for use as electromagnetic wave absorbing materials in the frequency range 1-3GHz (for hand-held cellular phone and wireless LAN).
