The structural and magnetic properties of doped ferrite Zn 0.3 Cu 0.7 Fe 1.5 Ga 0.5 O 4 have been studied by means of the neutron diffraction method at high pressures up to 4.7 GPa and in temperature range 300–425 K. By increasing the temperature a
In this chapter, we introduce a comprehensive study of the effect of both particle size and doping (Ga, Zn, and Sm) on the structural and magnetic properties of bulk and nanonickel ferrites. Different techniques; X-ray powder diffraction, Mossbauer e
