Recently, new magnetic material has been developed to meet the demands of
miniaturization and high performance of electronic attachment. P/M (Powder
metallurgy soft magnetic material with a high-resistance surface layer can
improve efficiency of electronic machine by reducing core loss at AC magnetic
field(1),(2). In addition, P/M process is expected to reduce the production cost
because it is produced near net shape, with almost no raw material loss(3).
Moreover, it has high recycle efficiency compared with traditional electrical steel
sheets so that it can return to original powder by crushing.
