Influence of Ni2+ and Sn4+ ions content on the microstructure and magnetic properties of the NiCuZnSn ferrite materials

With the development of miniaturisation and high performance of electronic devices, soft magnetic ferrite materials are required to have more excellent magnetic properties such as higher permeability and lower magnetic loss. The task of developing new soft magnetic ferrites with superior magnetic properties is very important. In this study, Ni0.30+xCu0.12Zn0.58SnxFe1.96-2xO4 (x = 0, 0.05, 0.10, 0.15, 0.20, 0.25) soft magnetic ferrite materials were prepared by a simple and economical solid phase method. By analysing the physical phase and microscopic morphology of all the ferrite materials, it is clear that the prepared samples are all in a single spinel phase. When at x = 0.05, this ferrite sample exhibits exceptional magnetic characteristics. The real part of the permeability (mu') is consistently the highest in the 100-1000 kHz band and has a maximum value of 1369.67 at 100 kHz. The mu' of this ferrite sample is improved compared to the undoped sample. Additionally, this sample has the least power loss (P-cv) of 501.87 mW/cm(3) at 1000 kHz among other similar samples. It can be seen that the addition of Ni and Sn is beneficial in reducing P-cv. From the M-H curves, it can be seen that NiCuZnSn ferrites have higher M-s and lower M-r and H-c, indicating that this material has standard soft magnetic properties. This work has shown that tiny quantities of Ni and Sn may be substituted for small amounts of Fe in the NiCuZn ferrite materials to increase permeability (mu') while reducing power loss (P-cv). Therefore, this NiCuZnSn ferrite material can be used as a potential candidate for the manufacturing of electronic devices in the field of communication devices, networks and electronic devices
