1 Magneto-infrared system

The system is the result of long-term in-house development and prototyping. It currently achieves simultaneous operation at magnetic fields of 0-12 T (with compatibility for higher-field magnets), temperatures of 2-300 K, and a wavelength range of 1-200 μm (50-10,000 cm^-1), with a signal-to-noise ratio of 2×10⁴ (0.005% noise) and a spectral resolution of 0.02 meV. It further supports in-situ linear and circular polarization resolution, and has been providing long-term open access to users across disciplines worldwide. The current beam spot size is ~1 mm, suitable for samples larger than 0.1 mm. A microscopy-based version of the magneto-infrared spectroscopy system is under development and is expected to be available by 2028.
