Description

The insulating state of k-(BEDT-TTF)2Cu[N(CN)2]I salt appearing at ambient pressure at low temperatures is suppressed by hydrostatic pressure. The resistive measurement showed that in high-quality crystals the emerging metallic state reveals superconductivity. The superconducting state with the transition temperature of about 8 K is stable at pressures higher than 0.1 GPa

Abstract (Russian)

Изолирующее состояние соли k-(BEDT-TTF)2Cu[N(CN)2]I, возникающее под давлением окружающей среды при низких температурах, подавляется гидростатическим давлением. Измерения удельного сопротивления показали, что в совершенных кристаллах появляющееся металлическое состояние демонстрирует сверхпроводящие свойства. Сверхпроводящее состояние с температурой перехода около 8 К является стабильным при давлениях выше 0.1 ГПа
