Unveiling the impact of anti-site defects in magnetic transitions of few-layer MnBi2Te4 by operando heating
Xinyu Chen, Jingjing Gao, Shuang Wu +11
As the first experimentally discovered intrinsic magnetic topological insulator, MnBi2Te4 has attracted widespread attentions, providing a unique platform for the exploration of to…
Observation of High-Order Anisotropic Magnetoresistance in a Cubic Ferromagnet
Haoran Chen, Yue Chen, Yizi Feng +10
High-order anisotropic magnetoresistance (AMR) is observed up to the 18th harmonic in cubic Fe(001) thin films, overturning the long-standing paradigm that only two- and four-fold…
Intrinsic layer polarization and multi-flatband transport in non-centrosymmetric mixed-stacked multilayer graphene
Kai Liu, Yating Sha, Bo Yin +20
Graphene multilayers exhibit electronic spectra that depend sensitively on both the number of layers and their stacking order. Beyond trilayer graphene, mixed stacking sequences (a…
Cascade of Even-Denominator Fractional Quantum Hall States in Mixed-Stacked Multilayer Graphene
Yating Sha, Kai Liu, Chenxin Jiang +15
The fractional quantum Hall effect (FQHE), particularly at half-filling of Landau levels, provides a unique window into topological phases hosting non-Abelian excitations. However,…
Quantized Topological States and Parity Anomaly in Intrinsic Quantum Anomalous Hall Insulator MnBi2Te4
Zhongxun Guo, Jingjing Gao, Zhiwei Huang +22
When thinned down to just a few atomic layers, the layered magnetic topological insulator MnBi2Te4 offers an exceptional platform for exploring a wide range of topological phenomen…
