a, Raman spectra of the silicon Raman mode centered around 525 cm−1 with −80 V (blue) and 80 V (red) applied to the strain cell. b, Raman shift of the silicon Raman mode as a function of the piezo voltage. c, Linear dichroism versus temperature for a non-strained, thin bulk FePSe3 flake on the strainer setup, showing the shift (~10 K) in the transition temperature due to the increased thermal load of the strainer. The x-axis shows the nominal thermocouple reading.
