Advanced Magneto-Optics Lab

Equipment

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.;

In both 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).

• 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).
