| Research Abstract |
According to the rapid development of industrial devices, the new high frequency magnetic materials are expected. In this research, the nano-composite hetero-structured films were studied with magnetic particles embedded in ceramic matrix. The TiN ceramic matrix was chosen for its high thermal and chemical stability. The Co-TiN films show good soft magnetic properties in a wide-range of Co content : Co_x-(TiN)_<1-X> (x=40-80 at.%), and exhibit good thermal stability after the annealing at 600℃. Moreover, the electromagnetic noise suppressor of soft Co-TiN magnetic films has been demonstrated successfully.
