説明
Though it is well known that the valency state of cations in Mn-Fe ferrites has much effects on their electric and magnetic properties, we have never had a method suited to analyze the valency state. In this paper, the method is shown by which the valency state of cations in those ferrites may be analyzed chemically. And then, appropriateness of the method is discussed in comparison with the results of electric resistivity and disaccomodation of those ferrites and we may conclude that the method gives reasonable results. From the results analysed chemically by the method, it is also shown that actual Mn-Fe ferrite has a chemical composion Mn2+1-x-yMn3+yFe2+x+y-zFe3+2-y+z_??_3/8zO4+z/2 and the amount of y and z depending on firing conditions of the ferrite gives much effects on electric resistivity and disaccomodation of those ferrites.
