Electric field stimulation setup for photoemission electron microscopes
REVIEW OF SCIENTIFIC INSTRUMENTS 86 (2015), 083702
Manipulating magnetisation by the application of an electric field in magnetoelectric multiferroics represents a timely issue due to the potential applications in low power electronics and the novel physics involved. Thanks to its element sensitivity and high spatial resolution, X-ray photoemission electron microscopy is a uniquely suited technique for the investigation of magnetoelectric coupling in multiferroic materials. In this work, we present a setup that allows for the application of in situ electric and magnetic fields while the sample is analysed in the microscope. As an example of the performances of the setup, we present measurements on Ni/Pb(Mg0.66Nb0.33)O3- PbTiO3 and La0.7Sr0.3MnO3/PMN-PT artificial multiferroic nanostructures.
