摘要：

The layered organic metals alpha-(BEDT-TTF)(2)MHg(SCN)(4) (M=K, Rb, Tl) show resistance decrease with the onset at 0.3 K, 0.5 K and 0.1 K, respectively. These decreases are suppressed by a magnetic field less than 0.2 T and considered as an occurence of superconductivity, although zero resistance is not achieved. We discuss this incomplete superconducting transition in terms of the vicinity to a superconductor-insulator transition caused by the elevated sheet resistance due to the antiferromagnetic ordering at 8 similar to 10 K.
