Hexaferrite Co(2)Z was synthesized through the modified Pechini method. Partially oriented samples were obtained after consolidation with uniaxial pressing and calcination/sintering at 1300 degrees C/1330 degrees C. The sample composition and morphology was identified with X-ray diffractometry (XRD) and scanning electron microscopy (SEM) with energy-dispersive X-ray spectrometry (EDS). MFM studies of the single grains revealed a domain structure with 0.7 mu M wide. The Co(2)Z static magnetization was measured with a vibrating sample magnetometer (VSM), and was used to calculate a single grain domain with a thickness of 4.8 mu m. This result is in good agreement with SEM observations of the single grain thickness.
