Summary: This article investigates the synthesis, structural features, magnetic properties, and microwave properties of hard/soft SrNiZr/CFO nanocomposites. The samples were prepared using a sol-gel auto-combustion approach and their structural characteristics were verified through XRD, SEM, TEM, and HR-TEM techniques. The magnetic measurements showed good exchange coupling between the hard and soft phases at room temperature, but weak coupling at low temperature. The electromagnetic properties and the correlation with the magnetic phase ratio were also analyzed.

Summary: In this study, spinel Ni-Zn ferrites with excellent microwave absorption properties were synthesized and their absorption characteristics and interaction mechanisms were investigated. The results showed that S-NZFO had a wide effective absorption bandwidth and high saturation magnetization, while H-NZFO had small particle size and high complex permittivity. Both materials demonstrated potential as efficient microwave absorbers in military and civilian applications.

Summary: The Co1-xNixFe2O4 ferrite material samples were successfully synthesized by the sol-gel combustion method. Analysis using XRD and Raman spectroscopy revealed changes in the structure and magnetic properties with the doping of Ni2+ ions, including lattice distortion and destruction of the ferromagnetic sequence. The decrease in grain size due to Ni doping was observed to impact space charge polarization, with implications for microwave absorption properties.
