Originální abstrakt

A ceramic material consisting of two distinct compositions, (Al₀.₂Co₀.₂Cr₀.₂Ni₀.₂Fe₀.₂Zn₀.₂)₃O₄ and (Al₀.₂Co₀.₂Cr₀.₂Ni₀.₂Fe₀.₂Mg₀.₂)₃O₄, was synthesized using solid-state synthesis of the powder, followed by cold pressing and cold isostatic pressing. Pressed green bodies were sintered at two different temperatures (1223 K and 1423 K). The study examined the effects of composition and sintering temperature on the structural and magnetic properties of the materials, utilizing X-ray diffraction (XRD) analysis and SQUID magnetometry. High-entropy oxide samples with a single-phase spinel structure (space group Fd-3m) were prepared. Analysis of the magnetic properties revealed that the samples exhibited soft magnetic characteristics, indicating potential applications in the development of reversible magneto-active composites, such as magnetorheological elastomers.
