The application to magnetic recording of Ba-ferrite epitaxially coated with Spinel-ferrite, which is called SEB particles, was investigated. The results obtained are as follows: The lattice images of SEB particles showed that the Spinel-ferrite(Co-ferrite) was epitaxially crystallized on the surface of Ba-ferrites.
The saturation magnetization of the SEB powders was increased about 10% for that of the Ba-ferrite powders before reaction.
The output voltage in short wavelength of the tapes with SEB powders was lower than that of the oter tapes, MP tapes and Baferrite tapes. We considered this is probably due to the mixture formation by an incomplete SEB reaction, particle distribution and formation distribution of any particles etc.
