Ferrite is a magnetic ceramic-like substance that can be used in a variety of electronic devices. Ferrites are polycrystalline that is, they are made up of many microscopic crystals they are tough, brittle, iron-rich, and often grey and black in color. They are formed by the combination of iron oxide with one or more metals. Magnetization refers to the concentration of magnetic dipole moment that appears in a magnetic substance when it is in proximity to a magnet. This research work includes the study and comparison of magnetic properties of Zn doped Ni ferrites and Cu doped Ni ferrites prepared using sol-gel method. At first Zn doped Ni ferrite samples were considered. Magnetic traits using vibrating sample magnetometer were inspected. Zn content with x=0, 0.3, 0.5, 0.7 and 1 were reviewed for magnetic parameters. Later, Cu doped Ni ferrite with values ranging from x= 0, 0.5, 1 were plotted. The M-H hysteresis curves of the samples reveal substantial increase in saturation and coercivity. These ferrites are utilized in implementation in engineering to make systems and improve their function.
