Magneto-optics

The interaction of light with matter offers an invaluable tool to characterize the properties of materials and, at the same time, can be exploited for applications in optical communications, data storage, or sensing.

FErroelectric and DiElectric Laboratory

Our FErroelectric/DiElectric laboratory is specially designed to characterize all kind of functional properties of ferroelectric and multiferroic thin films.The following characterizations can be performed:

All these characterizations can be implemented in three experimental setups, to perform respectively room temperature, high and low temperature, or cryogenic magnetoelectric measurements:

      Room temperature measurements: a table with micropositioners (Signatone S-2 and S-725) and tungsten needles of several diameters and hardnesses is used. A Faraday box is available to shield environmental noise when required.

      Low and high-temperature probe station: a 4-probes station able to reach from down to 5 K to ca. 1000 K with access to laser illumination.

 

      Cryogenic measurements (T>1.6K): they are performed inside a Physical Property Measurement System Quantum Design Co.) with a Multifunction probe suitably adapted (shielded cables with low thermal losses: Cryo cable – type SS, Lakeshore Co.). This system contains a superconducting magnet which allows to carry out all the electric measurements under magnetic fields up to 9T, thus allowing magnetoelectric characterization under high magnetic field.
