Magnetic force microscopy study of domain walls in Co{sub 2}Z ferrite
Graphical abstract: - Highlights: • Hexaferrite Co{sub 2}Z is synthesized through the modified Pechini method. • Magnetic domains are observed in anisotropic Co{sub 2}Z single grain using MFM. • Observed single grain domain thickness is in good agreement with Dotsh model. - Abstract: Hexaferrite Co{sub 2}Z was synthesized through the modified Pechini method. Partially oriented samples were obtained after consolidation with uniaxial pressing and calcination/sintering at 1300 °C/1330 °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 μm wide. The Co{sub 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 μm. This result is in good agreement with SEM observations of the single grain thickness.
