Uniaxial small-linewidth hexagonal ferrite material and preparation method thereof
The invention discloses a uniaxial small-linewidth hexagonal ferrite material and a preparation method thereof, and belongs to the technical field of ferrite material preparation. The preparation method comprises the following steps: presintering to generate Cu18H hexagonal ferrite powder, adding a SiO2 additive, carrying out high-energy ball milling, orienting submicron powder obtained by ball milling in a magnetic field molding press, and sintering to generate the high-density textured Cu18H hexagonal ferrite material. According to the uniaxial small-line-width Cu18H hexagonal ferrite material and the preparation method thereof provided by the invention, the preparation process is a traditional solid-phase reaction method, the operation is simple, and the process is mature; the prepared Cu18H hexagonal ferrite material has the characteristics of high density (rho is greater than or equal to 5.3 g/cm < 3 >), high saturation magnetization (4piMs is greater than or equal to 1400 G), high remanence ratio (Mr/Ms is greater than or equal to 0.6), high magnetocrystalline anisotropy field (Ha is greater than or equal to 9kOe) and low ferromagnetic resonance line width (deltaH is less than or equal to 320Oe), and is suitable for the design of a self-biased circulator so as to reduce the weight and the volume of a transceiver module of a communication system.
