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.
