Superconductivity under high pressure in the binary compound CaLi2 (original) (raw)

Superconductivity in the binary compound CaLi2 under high pressure was investigated, revealing contrasting behavior with classical expectations for simple metals. The research indicates that CaLi2 exhibits superconductivity under extreme pressures, with superconducting transition temperatures increasing with pressure, challenging the traditional understanding of superconducting responses in elemental metals. Results from x-ray powder diffraction and electrical resistance measurements at various pressures provide detailed insight into the structural and electronic changes associated with superconductivity in this compound.
