Investigation on mechanical properties of ferromagnetic amorphous ribbon

Ferromagnetic amorphous ribbon is a novel material used in the magnetic fluxgate sensor microsystem. Its mechanical, electrical and magnetic properties are critical to the properties of the sensor. In this paper, the mechanical properties of the amorphous ribbon are investigated by nanoindentation, and the obtained results are compared with the measuring results of tensile test. Experiment results show that nanoindentation load-displacement curve can present plastic and elastic deformation, and with the increase of the depth of indentation, the measuring results of elastic modulus and hardness are influenced by the underlying glue layer and the substrate.
