Bruker FTIR spectrometers are coupled to SCM3 and resistive magnet in cell 8.
IR transmission (reflectance) measurements can be carried out in magnetic fields up to 35T (17.5T). With a variety of detectors, beamsplitters and light sources, the frequency range of 10-6,000 cm-1 (far-IR to mid-IR) can be covered in magnetic fields, with a resolution better than 0.03 cm-1. Measurements are available in the Faraday geometry (magnetic field perpendicular to the sample) at a temperature range of 4.2-8 K at SCM3 and at 4.2 K in cell 8. Four samples can be loaded to the sample probe in one cool-down in SCM3 (17.5 T magnet) for both transmission and reflectance experiments, whereas one sample can be measured for one cool-down in 35 T magnet in cell 8 for transmission experiments. Typically the relative noise-to-signal ratio can be lower than 0.1%, which varies with the transmission and reflectance signals from samples. New capabilities of IR measurements are being developed besides those described above. Please contact Zhiqiang (Jason) Li for updates.
