摘要
The metal-insulator transitions occur at 190K and 20K for (BEDT-TTF)(2)MM'(SCN)(4) [M=Rb, M'=Co,Zn] and [M=Cs, M'=Co,Zn], respectively. The former transition at 190K might originate from electron-correlation with lattice modulation, suggested by the measurements of magnetic susceptibility and X-ray structure at low temperature. This transition temperature is elevated with applying pressure due to the increase of U/4t.
