Structuraland magnetic properties of CoFe۲-xAlxO۴ nanoparticles

Cobalt ferrite duo to its high coercivity, moderate saturation magnetization, high magneto crystalline anisotropy,high chemical and mechanical hardness is one of the good candidates for high-density recording media, sensors,transformer cores, and microwaves devices [۱-۲]. The substitutionof non-magnetic Al۳+ions in cobalt ferrite can reduce the loss factor, and thus improve the efficiency of microwave devices and transformers applications. The present work reports the synthesis of CoFe۲-xAlxO۴nanoparticles and studyof their structural and magnetic properties through X-ray diffraction and magnetization measurements.
