Co-Ti共掺杂对Y型六角铁氧体陶瓷磁电性能的影响
The Effects of Co-TiCo-doping on the Magnetic and Electrical Propertiesof Y-type Barium Hexaferrite Ceramics
摘要
Abstract
The magnetic properties of Co-Tico-doped Y-type bariumhexaferrite ceramicsBa2 Mg2 CoxTix Fe12-2x O22(x=0~2) prepared through solid-state reaction have beeninvestigated .X-ray diffraction,scanning electron microscopy and vibrating sample magnetometer were used to investigate the crystalstructure,Surface morphology and magnetic properties.The results show thatwith minor doping addition,the Co-Tiatoms have been incorporated into the lattice matrix to form solid-state solutions.It has been shown that the samples gradually appearmixed phaseatx>0.5.TheSEM shows that the grain sizes of the samples have been significantly reduced with the rise of doping amount.It is found that all the samplesare ferromagnetic at roomtemperature.Theelectrical property analysis results show that there sistivity of the Co-TicodopedY- type barium hexaferrite ceramics can be enhanced by Co-Tico-doping.The sample with x = 2 has been hanced about 4 or ders in magnanitude.关键词
