8) Giant Shubnikov de Haas Oscillation in two-Dimensional Organic Conductor,τ-(EDO-S,S-DMEDT-TTF)2(AuBr2)1+y,(y~0.75)

The Shubnikov de Haas oscillation in two-dimensional organic conductor, τ-(EDO-S, S-DMEDT-TTF)2(AuBr2)1+y,(y~0.75) was first observed. Red and Blue colors show the data of the two samples. The undulation is obvious in two samples, which indicates the existence of other oscillation. The giant oscillation is due to the fact that the system is already at the Landau's n=2 state.
