Abstract
The samples of highly coercive ferrites Sr1 − xSmxFe12 − xZnxO19 (0 ≤ x ≤ 0.4) with the structure of magnetoplumbite have been obtained by the solid-phase method. It has been determined that the samples Sr1 − xSmxFe12 − xZnxO19 are single-phase at x ≤ 0.2 and contain the impurity phases of α-Fe2O3, SmFeO3, and ZnFe2O4 at x ≥ 0.3. In the magnetic fields up to 14 T, the specific magnetization has been measured and the values of coercive force (σHc) have been determined at 5 and 300 K. It has been shown that semiconductor electroconductivity of single-phase samples Sr1 − xSmxFe12 − xZnxO19 gradually decreases with the increase in the degree of substitution of x from 0 to 0.2.
