论文摘要
我们报告了Laalge，lorentz侵入的II型WEYL半含量和倾斜的Weyl锥的量子振荡测量值。在费米表面检测到非常小的准粒子质量和非常高的费米速度。尽管已经观察到三个主要频率，但尽管没有2D结构特征，例如范德华键，但两个费米表面表的角度依赖性表明可能二维（2D）特征。这样的导电状态可以为磁性磁力（R = CE，PR）材料中的低维偏振电流提供一个良好的平台。
We report quantum oscillation measurements of LaAlGe, a Lorentz-violating type-II Weyl semimetal with tilted Weyl cones. Very small quasiparticle masses and very high Fermi velocities were detected at the Fermi surface. Whereas three main frequencies have been observed, angular dependence of two Fermi surface sheets indicates possible two-dimensional (2D) character despite the absence of the 2D structural features such as van der Waals bonds. Such conducting states may offer a good platform for low-dimensional polarized spin current in magnetic RAlGe (R = Ce, Pr) materials.
