采用溶胶-凝胶自蔓延法制备Co-Zr离子共掺BaFe12O19,并研究不同掺杂量和煅烧温度对样品微结构和磁性能的影响.利用X射线衍射仪、扫描电镜测试了样品的相结构和微观形貌,其宏观静态磁性用振动样品磁强计进行表征.研究发现热处理温度对掺杂前后的M型钡铁氧体宏观磁性有决定性影响,其中BaFe10Co1.0Zr1.0O19在1100℃保温4h,矫顽力H(c)为136 Oe,但是饱和磁化强度Ms仅32 emu/g;BaFe10.4Co0.8Zr0.8O19在1100℃保温4h,矫顽力为606 Oe,Ms增加到48 emu/g.这说明M型钡铁氧体的磁性能可以实现从传统的永磁到近软磁这样大范围的调控,使其拥有更广泛地应用空间.
