The general behavior of majrn»!it< (iron ferrite) at its low temperature transformation (ca 1!8°K) is reviewed. One of the properties which undergoes a largr change is the magnetocrystailine snisotropy, which is larger in magnitude and has a lower symmetry below the transformation. The magnetic symmetry axis below the transition tempeiature can be predetermined by cooling a single crystal throu...

The synthesis of magnetic nano-sized spinel ferrites has become an important area research, due to their several potential applications. In this work, CoFe2O4 nanoparticles were synthesized by the co-precipitation method. Structural, magnetic, and photocatalytic properties cobalt analyzed based on chemical composition considering biological properties. Structural morphological investigated X-ra...

Abstract Ferrites are the most widely used microwave absorbing materials to deal with threat of electromagnetic (EM) pollution. However, lack sufficient dielectric loss capacity is main challenge that limits their applications. To cope this challenge, three high-entropy (HE) spinel-type ferrite ceramics including (Mg 0.2 Mn Fe Co Ni )Fe 2 O 4 , Cu and Zn were designed successfully prepared thro...
