The fabrication of the polymer-bonded composites of a Fe-Co based alloy and the characterization of their magnetic and mechanical properties is presented. Large compressive strength of 42 MPa is obtained for the composites, which indicates a solid bonding of flake-type powders by the polymer.

The investigation of the magnetic and magnetostrictive properties of amorphous Tb-Fe thin films as functions of sputtering conditions such as the substrate thickness, input power, sputtering time and coverage area ratio of coated thin film to substrate is reported. It was seen that at sputtering conditions corresponding to a high thin-film/substrate temperature, the macroscopic tensile and an annealing effect are high, causing the magnetostriction sensitivity to increase at low magnetic fields, coercivity and remanence ratio.
