Technology of preparation of (CoFe)/Cu superlattices by magnetron sputtering is discussed. The parameters of growth have been obtained which allows to get superlattices with very high magnetoresistance. Methods of characterization of superlattices are described. Microwave magnetoresistance in millimeter waveband is measured by transmission method. The record value of microwave magnetoresistance exceeding 80% is obtained.
