Low-linewidth ferrite material with high magnetic conductivity and high dielectric constant and preparation method thereof
The invention belongs to the field of electronic materials, and particularly provides a low-linewidth ferrite material with high magnetic conductivity and high dielectric constant and a preparation method of the low-linewidth ferrite material, and miniaturization and high performance of a microwave device can be realized when the ferrite material is applied to the microwave device as a substrate material. According to the invention, the NiCuZn ferrite material is obtained through component regulation and control: Ni0. 6Cu0. 224Zn0. 176-xTi2xFe1.392-xO3.992 spinel ferrite material, high-Ni-content ion substitution enables the material to have a high magnetic conductivity characteristic (the magnetic conductivity mu 'is greater than or equal to 180) in a frequency band of 1 MHz to 10 MHz, and Ti ion substitution enables the material to have a high dielectric constant characteristic (the dielectric constant epsilon' is greater than or equal to 25) in a frequency band of 1 MHz to 300 MHz; meanwhile, the iron-deficient formula prevents the generation of Fe < 2 + > ions and reduces the magnetic loss caused by the Fe < 2 + > ions, so that the material has relatively low ferromagnetic resonance line width (delta H is less than or equal to 135Oe); and finally, the microwave substrate material with high magnetic conductivity, high dielectric constant and low ferromagnetic resonance line width is obtained, so that miniaturization and high performance of microwave devices are realized, and the application requirements of high-frequency transmission are met.
