Role of Cr3+ ions on the microstructure development, and magnetic phase evolution of Ni0.7Zn0.3Fe2O4 ferrite nanoparticles

“…Many researchers [40,41] have reported similar observations. The increase of i with temperature can be explained as follows.…”

Magnetic properties of NiCuZn ferrites synthesized by oxalate precursor method

“…7, 8 variation of m 0 and m 00 with frequency in the range 20 Hz to 1 MHz, for the composition Ni xCu (0.45Àx) Zn 0.55 Fe 2 O 4 , are shown. Rado [21] and others [22][23][24][25] observed high-frequency dispersion and absorption in m i and attributed it to rotational resonance in the combined anisotropy and demagnetizing fields while the low frequency dispersion was attributed to the domain wall displacement. From Figs.…”

Influence of calcination temperature on the morphology and magnetic properties of Ni–Zn ferrite applied as an electromagnetic energy absorber

“…The X-band frequency radar has been of great interest to the military sector because it allows for high resolution imaging and greater precision target identification [3]. These applications are due an excellent combination of magnetic and dielectric properties, which can be adjusted by adding divalent and/or trivalent metallic ions [4] or by modifying their production process [5].…”
