ac susceptibility measurements of the charge-density-wave (CDW) compound alpha-(BEDT-TTF)(2)-KHg(SCN)(4) at magnetic fields, mu0H >23 T, above its Pauli paramagnetic limit, reveal unambiguously that the magnetic hysteresis observed previously within this CDW phase is diamagnetic and can only be explained by induced currents. It is argued that the ensemble of experimental techniques amounts to a strong case for dissipationless conductivity within this phase.
在高于其泡利顺磁极限（μ₀H > 23 T）的磁场下，对电荷密度波（CDW）化合物α-(BEDT-TTF)₂-KHg(SCN)₄进行的交流磁化率测量明确显示，先前在该CDW相内观察到的磁滞是抗磁性的，并且只能由感应电流来解释。有人认为，这一系列实验技术有力地证明了该相内存在无耗散导电性。
