Characterization of magnetic tunnel junctions (MTJ) with magnetostrictive free layer materials

Description

Magnetic tunneling junctions (MTJs) incorporating magnetostrictive free layer materials are developed and characterized for the application as highly sensitive strain sensors. Gauge factors of the order of 400-600 have already been demonstrated compared to typical values of 2-4 for metal film based strain sensors. Here, different magnetostrictive materials such as amorphous FeCoSiB alloy and polycrystalline Ni films have been investigated in order to characterize and optimize the MTJ based sensor properties
