Film nanostructures multilayer magnetic screens
The efficiencies of cylindrical configuration magnetic shielding screens based on the NiFe/Cu multilayer film nanostructures were investigated. The screen was placed into uniform magnetic field perpendicular to the axis of the cylindrical screen created by means of Helmholtz coils. The dependence of magnetic field induction from the distance to the screen center was measured with the help of Hall probe. It was shown that the multilayer film structure magnetic screens possess shielding efficiencies 2 - 3 times higher than the comparable thickness permalloy ones. The installation based on educational laboratory equipment and research technique are presented.
