Intrinsic topological phases in MnBiTe tuned by the layer magnetization
Yue Li, Yadong Jiang, Jinlong Zhang +3
The interplay between band topology and magnetic order could generate a variety of time-reversal-breaking gapped topological phases with exotic topological quantization phenomena,…
Ice-rule made manifold: phase transitions, topological defects and manifold restoration in two-dimensional artificial spin systems
Gavin M. Macauley, Gary W. Paterson, Yue Li +3
Artificial spin ices are arrays of correlated nano-scale magnetic islands that prove an excellent playground in which to study the role of topology in critical phenomena. Here, we…
Heisenberg pseudo-exchange and emergent anisotropies in field-driven pinwheel artificial spin ice
Gary W. Paterson, Gavin M. Macauley, Yue Li +8
Rotating all islands in square artificial spin ice (ASI) uniformly about their centres gives rise to the recently reported pinwheel ASI. At angles around 45, the antif…
Origin of topologically trivial states and topological phase transitions in low-buckled plumbene
Yue Li, Jiayong Zhang, Bao Zhao +2
Combining tight-binding (TB) models with first-principles calculations, we investigate electronic and topological properties of plumbene. Different from the other two-dimensional (…
Superferromagnetism and domain-wall topologies in artificial 'pinwheel' spin ice
Yue Li, Gary W. Paterson, Gavin M. Macauley +9
For over ten years, arrays of interacting single-domain nanomagnets, referred to as artificial spin ices, have been engineered with the aim to study frustration in model spin syste…
