- Piezomagnetic materials in composition $Ni_{0.284}Zn_{0.549}Cu_{0.183}Fe_{1.984}O_4$ were prepared by mixed oxide method at 1100°C. Powder X-ray diffraction studies confirm the crystalline nature of the synthesized $Ni_{0.284}Zn_{0.549}Cu_{0.183}Fe_{1.984}O_4$ piezomagnetic material. The crystallite size is calculated to be 19.332 μ m using the Debye-Scherrer formula. The surface morphology and particle size of the samples has been studied by scanning electron microscopy. The thermal stability and decomposition behaviour of $Ni_{0.284}Zn_{0.549}Cu_{0.183}Fe_{1.984}O_4$ piezomagnetic material have been studied by thermogravimetric analysis at a heating rate of 15°C/min. The effective activation energy of the prepared composite was calculated using single heating rate methods: Broido's and Coats-Redfern methods. Dielectric properties of $Ni_{0.284}Zn_{0.549}Cu_{0.183}Fe_{1.984}O_4$ piezomagnetic material have been studied in a wide range of frequencies and temperatures. The magnetic behavior of $Ni_{0.284} Zn_{0.549} Cu_{0.183} Fe_{1.984}O_4$ piezomagnetic material at room temperature has been confirmed by vibrational sample magnetometer studies.
