From Mott insulator to ferromagnetic metal: a pressure study of Ca${}_2$RuO${}_4$

Fumihiko Nakamura, Tatsuo Goko, Masakazu Ito +7

We show that the pressure-temperature phase diagram of the Mott insulator Ca${}_2$RuO${}_4$ features a metal-insulator transition at 0.5GPa: at 300K from paramagnetic insulator to…
