Abstract

In order to investigate relationships between superconducting phase and charge ordered one, the uniaxial strain method is applied to the superconducting salt α-(BEDT-TTF) 2NH 4 Hg(SCN) 4 and the organic conductor α-(BEDT-TTF) 2CsCd(SCN) 4. Both salts preserve metallic states under a-axial strain and show insulating behaviours under c-axial strain. These results suggest that i) c-axial strain controls the electronic properties of the α-type salts, and ii) the insulating state in the vicinity of the superconducting phase of α-(BEDT-TTF) 2NH 4Hg(SCN) 4 is a charge ordered phase, as expected from the comparison in the lattice parameters with the charge ordered salt θ-(BEDT-TTF) 2 RbZn(SCN) 4.
