Diamond anvil cell based magneto-optical spectroscopy for quantum materials research

Quantum materials often exhibit exotic phases under extreme conditions such as low temperature, high magnetic field, and high pressure. Here, we report on the development of a magneto-optical setup that integrates a diamond anvil cell with a Quantum Design Physical Property Measurement System, enabling variable temperature (down to 2 K), high-pressure (up to 16 GPa) optical spectroscopy in a magnetic field (up to 14 T). Using topological material ZrTe₅ as an example, we showcase the capability of our setup. Specifically, we show the evolution of Raman peaks as a function of temperature, magnetic field, and pressure.
