Description
実施例２〜５
共沈反応後の共沈物（フェライト組成物）の組成が、Ca 1-x-y La x Ba y Fe 2n-z Co z O 19 ｛x＝0.5、y＝0.001〜0.2（表１に示す）、z＝0.30、n＝5.2｝になるようにBaCl2・2H2Oの使用量を変えて調整した溶液を、溶液１の代わりに使用した以外は実施例１と同様にして本発明のフェライト粒子（実施例２〜５）を作製した。
Examples 2-5
The composition of the coprecipitate after the coprecipitation reaction (ferrite composition) is, Ca 1-xy La x Ba y Fe 2n-z Co z O 19 {x = 0.5, y = 0.001~0.2 ( shown in Table 1), The ferrite particles of the present invention were the same as in Example 1 except that a solution prepared by changing the amount of BaCl 2 .2H 2 O used so that z = 0.30 and n = 5.2} was used instead of solution 1. (Examples 2 to 5) were produced.
