Abstract

Magnetization measurements performed on the charge-transfer salt α-(BEDT-TTF $)_{2}$ TlHg(NCS $)_{4}$ in pulsed magnetic fields reveal the existence of eddy current “resonances” in the high field state, indicating the presence of deep minima in the transverse magnetoresistivity. Their behavior can be explained qualitatively in terms of enhanced conductivity due to the quantum Hall effect.
