Title:
Neutron Depolarisation Imaging: {{Stress}} Measurements by Magnetostriction Effects in {{Ni}} Foils 
Abstract:
In this article we present first proof-of-principle neutron depolarization imaging measurements on Ni foils under mechanical stress. The magnetostrictive effect in Ni leads to a reorientation of the magnetic domains in the material depending on the applied force. This in turn leads to a change of the depolarization a neutron beam suffers from transmission of the sample. We propose to use this method as a new technique for the spatially resolved measurement of mechanical stress.
