E ffect of A l-substituted on particle size and magn etic properties of Ni۰.۶Co۰.۴Fe۲- xAlxO۴ (۰ x ۰.۳) ferrite nan oparticles

Synthesis of mix ed spinel ferrite nano particles to be one of the interes ting ¿elds of material science in material processing and technological applications, as the small size particles have some of the interesting propertie s as compared to bul k particles [۱]. In the spinel stru cture, the magnetic ions are distrib uted among two different lattice sites, tetrah edral (A) and octahedral (B) sites. T he magnetic properties of spinel f errites, such as transition temperature and saturation magnetic moment are strongly dependent on the distribution of cations and typ e of doping atom. Therefore, the magnetic pro perties of th ese materials can be t ailored by u sing the doping of the different transition metal cations. In the presen t work, we have study the effe ct of Al doping on structural and magnetical proper ties of Ni۰.۶Co۰.۴Fe۲-xAlxO۴ ( ۰ x ۰.۳) ferrite nanoparticles. S tructural a nd magnetic properties of Ni۰.۶Co۰.۴Fe۲-xAlxO۴ ferri tes nanoparticles have been studied by x-Ray diffraction (XRD) and vibrating sample magnetometer (VSM). Na noparticles of Ni۰.۶Co۰.۴Fe۲-xAlxO۴ ferrite were synthe sized using sol-gel method.
