Description :
The samples of various combinations of Y-type aluminium substituted calcium hexaferrite with composition Ca2Zn2Fe12-xAlxO22 (0≤x≤1) were synthesized by sol-gel autocombustion route by blending metal nitrates as oxidants accompanied with fuel like urea as reducing agent. The structural property is being analyzed by XRD and TEM. The synthesized samples are found to be in nanorange. The X-ray diffraction pattern at room temperature showed the prepared samples have a single Y-type hexagonal ferrite. The magnetic properties of the samples were studied by using Vibrating Sample Magnetometer(VSM). The magnetic properties are observed be improved upon those of the samples reported earlier. This confirm the more viability of such samples in the various applications of such as permanent magnet, microwave device materials and magneto-optic recording media.
