我们开发了准二维金属中发生磁击穿的角度相关磁阻振荡（AMRO）的分析模型。该模型考虑了准粒子在每个结处经历磁击穿和布拉格反射的所有贡献，并允许极其有效的数据模拟，可以与有机金属 kappa-ET2Cu(NCS)2 的最新实验结果进行比较。由闭合轨道和开放轨道产生的 AMRO 在低场下自然出现，并且该模型能够详细描述随着场增加而向击穿 AMRO 的过渡。
We have developed an analytical model of angle-dependent magnetoresistance oscillations (AMROs) in a quasi-two-dimensional metal in which magnetic breakdown occurs. The model takes account of all the contributions from quasiparticles undergoing both magnetic breakdown and Bragg reflection at each junction and allows extremely efficient simulation of data which can be compared with recent experimental results on the organic metal kappa-ET2Cu(NCS)2. AMROs resulting from both closed and open orbits emerge naturally at low field, and the model enables the transition to breakdown-AMROs with increasing field to be described in detail.
