Pressure Induced Stripe-order Antiferromagnetism and First-order Phase Transition in FeSe

P. S. Wang, S. S. Sun, Y. Cui +5

To elucidate the magnetic structure and the origin of the nematicity in FeSe, we perform a high-pressure ${}^{77}$Se NMR study on FeSe single crystals. We find a suppression of the s…
