【摘要】 采用固相反应法制备了掺钆的W型Ba_1-xGd_xZn₂Fe₁₆O₂₇（x=0⁰.20）铁氧体。利用X射线衍射仪及扫描电子显微镜对其晶体结构及微观形貌进行分析,使用振动样品磁强计对其磁性能进行研究。结果表明:1300℃时,不同Gd³⁺掺杂量下均形成了纯度较高的W型钡铁氧体,六角片状结构完整。随着Gd³⁺掺杂量的增加,样品的饱和磁化强度呈现先增大后减小的趋势,并且在x=10时出现最大值。更多还原

【Abstract】 Ferrite Ba_1-xGd_xZn₂ Fe₁₆O₂₇ powders were prepared by solid state method.Phase composition and particle appearance were analyzed with X-ray diffraction（XRD） and scan electron microscope（SEM）.Magnetic properties were analyzed with vibrating sample magnetometer（VSM）.It was found that powders crystallized in to W-type ferrite phase and formed W-type hexagonal plane ferrite at 1300℃.The saturation magnetization increased at first,and then decreased with the increasing of the Gd^{3 +} content,and they all have the maximum value when x = 0.10.更多还原
