详细的磁电阻测量已进行（BEDT-TTF）2 TlHg（SCN）4。本文分析了在低温下电子谱可能发生的变化，并讨论了与角度有关的半经典磁电阻振荡。一个自旋密度波提出的费米面的修改，使新的开放片出现，与所观察到的角磁阻振荡。还介绍了Shubnikov-de哈斯效应的一些细节，这些细节可以用磁击穿网络的存在来解释，与所提出的化合物的低温电子态一致
Detailed magnetoresistance measurements have been performed on (BEDT-TTF) 2 TlHg(SCN) 4 . An analysis of angle dependent semi-classical magnetoresistance oscillations is presented in connection with possible changes in the electron spectrum at low temperatures. A spin density wave is proposed to arise leading to a modification of the Fermi surface so that new open sheets appear, consistent with the observed angular magnetoresistance oscillations. Some details of the Shubnikov-de Haas effect are also presented which can be explained by the existence of a magnetic breakdown network, in agreement with the proposed low-temperature electronic state of the compound
