- Abstract
- Ion distribution is determined in a series of aluminum substituted lithium ferrites by carefully analyzing the powder X-ray diffraction patterns. A new finding is that Al+3's substitute the Fe+3's in tetrahedral sites as well as in octahedral sites of the spinel structure. The proper formula, then, is (Fe(+3)1-a Al(+3)a) [Li0.5+Fe1.5-(x-a+3)Al-x-a(+3)](4), where a is approximately 0.23x(2)+0.22x. The saturation magnetizations are calculated and compared with the measured values.
