Advanced optical techniques are essential for probing local structural, lattice, and magnetic properties in functional materials in a non-invasive way, offering powerful complementary insights to conventional transport measurements. Our OptiCool-based optical platform with home-made microscope integrates a suite of state-of-the-art functionalities, including: Raman spectroscopy Photoluminescence (PL), Second harmonic generation (SHG), Reflected magnetic circular dichroism (RMCD), Reflection spectroscopy, Photocurrent (PC) measurements. For each optical technique, this multifunctional platform supports: spatial mapping with 1 µm resolution, polarization-resolved excitation and detection, temperature control from 2 K to 350 K and Out-of-plane magnetic fields up to 7 T. We plan to expand its capabilities to include time-resolved techniques, such as time-resolved photoluminescence (TRPL) and ultrafast pump–probe spectroscopy.
This powerful and versatile setup enables comprehensive exploration of opto-spintronics, offering exceptional opportunities for PhD students and postdoctoral researchers interested in cutting-edge optical studies of quantum materials.
