ABSTRACT:
A highly corrosive-resistant metal having a high purity and a specific plane index is manufactured by ion beam deposition (IBD). A thin film having less defects and impurities is obtained. A magnetoresistant effect film for a magnetoresistant effect type magnetic head which is highly corrosion-resistant and exhibits excellent characteristics can be formed. In IBD according to the present invention, metal ions are provided with adjusted ion energy of 10 to 100 eV, and a metal having a particular mass number is selected by a mass separation electromagnet.
