Researchers from the Materials Growth and Measurement Laboratory (MGML) have published two Communications Materials papers supported by the GAČR Q-MAG project 25-15448S and featured in the Nature Collection “Condensed Matter Physics at High Pressure.” Combining crystal growth, high-pressure experiments, advanced characterization, spectroscopy, diffraction, and theoretical modelling, the studies reveal mechanisms governing pressure-tunable magnetism in van der Waals materials. They also highlight the successful collaboration between Charles University and the Institute of Physics of the Czech Academy of Sciences.
