Shubnikov - de Haas effect in the organic superconductor κ-(BEDT-TTF)2Cu[N(CN)2]Cl under pressure
Kartsovnik M.V., Biberacher W., Andres K., KushchN.D.
The interplane magnetoresistance of a layered organic superconductor k-(BEDT-TTF)2Cu[N(CN)2]X with X CI has been studied under pressure from 2 to 10 kbar. Shubnikov-de Haas oscillations have been found above 8 T, in the whole pressure range. The oscillation behavior is remarkably different from that observed in the isostructural Вг-containing analog. On the other hand, it resembles the features found previously in the k-(BEDT-TTF)2Cu(NCS)2 superconductor.
