چکیده انگلیسی
As a good gyromagnetic material for the applications in microwave and millimeter wave devices, Ba-hexaferrite quasi-single crystals have been successfully fabricated by using its nanosized single-domain crystallites as the starting materials via press-forming in magnetic field and sintering with minor liquid phase participation at 1280 °C for 10 h. The material is characterized by a highly densified and laminar fracture microtexture with a grain orientation degree of as high as 99% and shows a single-crystal magnetization behavior featured by 4πMs=4654 Gs, Ha=16800 Oe and Hc=120 Oe, suggesting a narrower ferromagnetic resonance linewidth ΔH than the counterpart fabricated by solid-state sintering technique.
