Abstract

The effects of uniaxial strain on ct-(BEDT-TTF)₂MHg(SCN) ₄ [M=K, NH₄] were systematically studied in order to clarify the difference of the electronic properties between K-salt and NH ₄-salt. Superconductivity like NH₄-salt was induced in K-salt by the c-axis uniaxial strain, while the density wave state like K-salt was induced in NH₄-salt by the a-axis uniaxial strain. The latter was confirmed by the angle dependent magnetoresistance measurement. It was found that the ratio of the in-plane lattice constant c/a plays a key role in dominating their electronic properties.
