摘要
Ion-substituted hexagonal M-type Ba ferrites are studied more and more frequently due to their large magnetic anisotropy and low production cost. In this study, hexagonal M-type Ba ferrite powder specimens with nominal composition Ba(ZnTi)(x)Fe(12-2x)O(19) (x = 0.0, 0.2, 0.6, 1.0, 1.4) were prepared via a new route by combining a chemical coprecipitation technique with a conventional ceramic technique. The magnetic properties and crystalline structures were studied by a vibrating sample magnetometer and an X-ray diffractometer, respectively. It was found that small quantities of ZnTi substitutions helped to form single-phase ferrite at a low calcination temperature, which has never been reported before. The magnetic properties were reduced obviously with the increase of x from 0.2 to 1.4, and the best content of substitutions in our case was x = 0.2.
