基于多朗德因子和低磁晶各向异性场的钒镍共掺杂钡铁氧体毫米吸波材料
Barium Ferrite Millimeter Wave Absorbing Material Based on Multiple Landé Factors and Low Anisotropic Field
摘要
Abstract
Both V5+ substituted and V5+-Ni2+ co-substituted barium ferrites have been prepared by sol-gel technology.The powder samples have been characterized by SEM,XRD,and XPS.The electromagnetic performance has been measured by the vector network analyzer.Compared with V5+ substituted system, the co-substituted ferrites show better microwave absorbing performance by decreasing the magnetic anisotropic field and introducing three different Landé factors (g).When the matching thickness of V5+-Ni2+ co-substituted barium ferrites is about 2 mm,the maximum absorbing bandwidth can reach about 8 GHz and the reflection loss (RL)is lower than-60 dB.Moreover,the co-substituted barium ferrites can achieve wider tunable frequency range, which makes it a promising absorbing material.关键词
