de哈斯{endash}货车阿尔芬在高达60 T的磁场中对{alpha}-（BEDT-TTF）{sub 2}KHg（SCN）{sub 4}进行的实验揭示了{beta}频率的振荡，这清楚地表明了在远高于扭结转变的磁场中的磁击穿。振荡幅度的研究表明，准一维和准二维费米面片之间的差距是显着小于预测的能带结构计算。我们考虑的自旋密度波嵌套和量子霍尔效应的影响。{版权} {美国物理学会}
de Haas{endash}van Alphen experiments on {alpha}-(BEDT-TTF){sub 2}KHg(SCN){sub 4} in fields of up to 60 T reveal oscillations of the {beta} frequency, a clear indication of magnetic breakdown at fields well above the kink transition. A study of the amplitude of the oscillations shows that the gap between the quasi-one-dimensional and quasi-two-dimensional Fermi-surface sheets is significantly smaller than predicted by band-structure calculations. We consider the implications for the spin-density-wave nesting and the quantum Hall effect. {copyright} {ital 1998} {ital The American Physical Society}
