Extended Data Fig. 6: Hysteresis in the strain-induced magnetic phase transition.
From: Reversible strain-induced magnetic phase transition in a van der Waals magnet
a, Intensity plot of PL as a function of strain as the piezo voltage is swept down from a high strain state. b, Integrated intensity of the entire spectral range as the strain is swept up (blue) and down (orange). To account for hysteresis in the piezostacks, we calibrated the strain using Raman sweeps in the same direction.
