Исследованы процессы, происходящие на атомном уровне вблизи поверхности феррита Mn0.6Zn0.3Co0.05Fe2.05O4, полученных в различных условиях - стандартной и специальной атмосфере. Предлагаемый способ насыщения цинком поверхностных слоев феррита частично восстанавливает не только химический состав, но и магнитную структуру вблизи поверхности ферритовых изделий
