| Research Abstract |
We have investigated soft-magnetic Fe based nanocrystalline films on aluminum substrates produced with Supersonic Free-Jet PVD(SFJ-PVD). The SFJ-PVD is a technique to deposit nanoparticles with supersonic gas flow and to form a thick coating film. With SFJ-PVD, we obtain a uniform high-density nanocrystalline Fe coating films. Nanocrystalline as-deposited film with good soft-magnetic properties(in-plane coercivity Hc=32.6-132 A/m and Saturation Magnetic Flux Density Bs=2.1-2.2 T) can be obtained by controlling grain size in film.
