Abstract
The high-frequency magnetic properties of strontium-partially-substitu ted Z-type magnetoplumbite with the composition 2CoO . 3Ba(1-x)Sr(x)O . yFe(2)O(3) mere studied using a hot-pressing technique. The best pro perties were obtained for a sample hot-pressed in oxygen, having x and y values of 0.5 and 10.8, respectively. The resonant frequency of tha t sample, corresponding to a mu '' maximum reaching 2.5 GHz, was signi ficantly larger than the value of 1.4 GHz previously reported for unsu bstituted Z, with the composition 2CoO . 3BaO . 12Fe(2)O(3). This resu lt implies that a new ferrite material, applicable in the gigahertz re gion, has been obtained.
