超流体 4He 上经典二维电子晶体的磁导率 sxx(B) 是非线性的。实验上,我们发现对 sxx(B) 的贡献,在恒定场 B 下,给出 sxx(B)?Jx,电流密度,而在恒定电流下,给出 sxx(B)?1/B。为了增加 Jx,由于与氦的强电子-波纹相互作用,霍尔速度 δH 在第一倒易晶格矢量处缓慢接近波纹速度 δl。然后,当ΔH>Δ1时,磁导率急剧下降。
The magnetoconductivity sxx(B) of a classical two-dimensional electron crystal on superfluid 4He is nonlinear. Experimentally, we find a contribution to sxx(B) which, at constant field B, gives sxx(B)?Jx, the current density, while at constant current, sxx(B)?1/B. For increasing Jx, the Hall velocity ?H slowly approaches the ripplon velocity ?l at the first reciprocal lattice vector, due to strong electron-ripplon interactions with the helium. The magnetoconductivity then decreases sharply for ?H>?1.
