Abstract: Doping of SrFe12O19 with 0.3 mol per unit of Ga3+ or In3+ ions causes a division in the 12K octahedral subspectrum. The splitting occurs due to a magnetic exchange interaction of some of the 12k2 Fe3+ ions. The random changes in the exchange interactions do not influence the 12k splitting.
