Disappearance and Survival of Superconductivity in FeSe under High Pressure

Kiyotaka Miyoshi, Shota Yamamoto, Atsushi Shiota +4

Superconductivity in FeSe was investigated under high pressure through the measurements of DC magnetization by using a diamond anvil cell. We successfully observed that the disappe…
