Applications of amorphous and nanocrystalline magnetic materials

A review of the main applications of amorphous and nanocrystalline soft magnetic materials is presented in this work. A good control of magnetic properties as anisotropy field, magnetostriction constant, initial susceptibility or switching field is very important in order to find suitable materials for applications. A wide spectrum of magnetostrictive and non-magnetostrictive soft magnetic amorphous materials applications is shown here. Each application is based on a specific property of the sample i.e. magnetic bistability in wires and magnetoelastic resonance in ribbons of magnetoelastic materials, giant magnetoimpedance and ferromagnetic resonance in non-magnetostrictive materials.
