Advanced Magneto-Optics Lab

Advanced Magneto-Optics Lab

Several home-made magnetometries based on the magneto-optic Kerr effect have been setting-up to study the static and dynamic magnetic properties of (opaque or semitransparent) artificial magnetic nanostructures:

  • Vectorial resolved room temperature Kerr magnetometer;
  • TRISTAN: variable temperature vectorial Kerr magnetometer, in which by using a prototype He-cryostat system with in-vacuum rotatory sample motion we could perform the magnetic characterization down 5 K up to 500 K.;
  • Time resolved vectorial magnetometry, with a wide range of dynamic frequencies (i.e., field sweep rates ranging from 1x10-6 T/s to 1x107 T/s).
  • M(R)OKE: dual magnetic & resistive optical Kerr magnetometer (for simultaneous measurements of M-H and MR-H loops).

In all set-ups, the magnetic measurements can be performed at different applied field angles (in the whole angular range with an angular resolution better that 0.5º).

Multi-purpose UHV growth/spectroscopy Lab

Multi-purpose UHV growth/spectroscopy Lab

The experimental equipment has two independent UHV chamber, the first one is an Organic Molecular Beam Epitaxy (OMBE) system used for the growth of the films of the organic molecules and metals in ultra high vacuum (UHV) conditions: 6 different evaporators for metals, one commercial (Omicron) triple evaporator for metals and one commercial (Kentax) triple evaporator for organics, plus preparation samples facilities (sputtering and annealing). The OMBE is connected to a second UHV chamber devoted to the in situ chemical and electronic structure analysis by means of X ray photoemission Spectroscopy (XPS), with a monochromated X ray source (Al K α line) and UV lamp for Ultraviolet Photoemission Spectroscopy (UPS), and Low Energy Electron Diffraction (LEED).
