${}^{13}$C NMR Study on Zero-Gap State in the Organic Conductor $\theta$-(BEDT-TTF)${}_2$I${}_3$ under Pressure

K. Miyagawa, M. Hirayama, M. Tamura +1

We present the results of our ${}^{13}$C NMR study of the quasi-two-dimensional organic conductor $\theta$-(BEDT-TTF)${}_2$I${}_3$ under pressure, which is suggested to be a zero-gap conduc…
