在脉冲磁场中对电荷转移盐\ensuremath{\alpha}-(BEDT-TTF${)}_{2}$TlHg(NCS${)}_{4}$进行的磁化测量表明，在高场状态下存在涡流“共振”，这表明横向磁阻存在较深的极小值。它们的行为可以定性地解释为量子霍尔效应导致的导电性增强。
Magnetization measurements performed on the charge-transfer salt \ensuremath{\alpha}-(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.
