FIELD: chemistry.
SUBSTANCE: invention relates to chemical technology. Method includes evaporation of mixture of water solutions of zinc- and iron-containing salts of carboxylic acid, taken in stoichiometric ratio. As carboxylic acid salts zinc formiate with composition Zn(HCOO)2·2H2O and iron formiate with composition Fe(HCOO)2·2H2O with further calcinations in air at temperature 650-750°C are used.
EFFECT: invention makes it possible to improve magnetic characteristics of obtained admixture-free nanodisperse material.
