Catalogue of flat-band stoichiometric materials

Nicolas Regnault et al.

Summary: Researchers established the Materials Flatband Database website by analyzing and screening existing three-dimensional stoichiometric materials, and found 345 potential candidate materials with flat bands near the Fermi level, which are different from known engineered materials. Through experiments and theoretical analysis, they successfully explained the origin of flat bands in five representative materials.

Spin-polarized hybrid states in epitaxially-aligned and rotated graphene on cobalt

Matteo Jugovac et al.

Summary: The strong interaction between graphene and ferromagnetic transition metals results in significant changes in the electronic states of graphene. A weakly-dispersing single-spin conical band feature is found in the graphene/Co interface, which is also present in rotated graphene domains on Co. The similarity in electronic properties between different graphene orientations is crucial for understanding the magnetic properties of graphene/Co interfaces.

Clarifying the apparent flattening of the graphene band near the van Hove singularity

Matteo Jugovac et al.

Summary: Graphene band renormalization near the van Hove singularity was investigated using angle-resolved photoemission spectroscopy on Li-doped quasifreestanding graphene on a cobalt surface. The absence of graphene band hybridization with the substrate, rigid energy shift representation of the doping contribution, and excellent electron-electron interaction screening on the metallic substrate provided a privileged perspective for this investigation. A clear ARPES signal was detected along the KMK direction of the graphene Brillouin zone, leading to an apparent flattened band. Simulations of the graphene spectral function demonstrated that the photoemission signal around the M point originated from the "tail" of the spectral function of the unoccupied band above the Fermi level. This interpretation suggests the absence of any additional strong correlation effects near the van Hove singularity, reconciling the mean-field description of the graphene band structure even in a highly doped scenario.

Quantum anomalous Hall octet driven by orbital magnetism in bilayer graphene

Fabian R. Geisenhof et al.

Summary: In this study, a state with a conductance of 2e(2)h(-1) in bilayer graphene was discovered, exhibiting magnetic hysteresis and QAH behavior driven by orbital magnetism that can be tuned via electric and magnetic fields. The observed octet of QAH phases in bilayer graphene displays peculiar ferrimagnetic and ferrielectric order characterized by quantized anomalous charge, spin, valley and spin-valley Hall behavior.

Engineering the spin conversion in graphene monolayer epitaxial structures

Alberto Anadon et al.

Summary: The study shows that a graphene monolayer between Co and a heavy metal (HM) can effectively preserve the spin current injected into the HM from the bottom Co layer, as revealed by thermo-spin measurements. The presence of the graphene monolayer leads to a reduction in the sum of spin Seebeck and interfacial contributions, independent of the spin Hall angle sign of the HM used.

Orbital magnetic states in moire graphene systems

Jianpeng Liu et al.

Summary: The study of moire graphene systems has attracted considerable attention due to their exotic phenomena, which are closely related to valley-spin-degenerate and topologically non-trivial flat bands. Experimental evidence suggests that unconventional orbital magnetism is exhibited when time-reversal symmetry is broken spontaneously in these systems. Theoretical perspectives on the correlated insulating states and quantum anomalous Hall phenomena are discussed in this Perspective, emphasizing the topological nature of moire flat bands.
