Abstract
Magnetisation measurements performed on the charge-transfer salt alpha -(BEDT-TTF)(2)TlHg(SCN)(4) in pulsed magnetic fields reveal the existe nce of eddy current ''resonances'' in the high field state, indicating the presence of deep minima in the transverse magnetoresistivity (or ideal conducting phases). Their behaviour can be explained qualitative ly in terms of enhanced conductivity due to the quantum Hall effect, w hich becomes possible even when quasi-one-dimensional carriers are pre sent.
