Study and Production of Magnetic Materials for IT Industry in DPR of Korea

摘要

The Democratic People's Republic of Korea is paying keen attention to studies of magnetic materials as well as semiconductor, metal and dielectric materials and to their industrial construction. Bases have been built up to produce such materials discovered in the first half of the precentury as magnetic material(Si steel) for eietric industry and magnetic materials (permalloy, ferrite, alnico, alnisi, cunife and cunico) for electric instrument,studies of ultra-advanced materials such as amorphous magnetic alloy, rare earth magnetic material and Nanocrystal magnetic material have been stregthened and their materials are now widely used in various fields of industry. Magnetic materials of superior quality for IT industry are produced at research instintutes under the Acedemy of Sciences and of universities.
