2024年11月22日 · We find that the single-layer CrBr3 film is insulating and acts likely as a vacuum barrier, the measured superconducting gap and vortex state on it are nearly the same as those of NbSe2 substrate.

2021年5月3日 · In this work, we report a detailed characterization of monolayer CrBr 3 on NbSe 2 (CrBr 3 /NbSe 2 hereafter) using low-temperature STM/STS and X-ray photo-electron spectroscopy (XPS).

2020年12月16日 · Here, we use MBE to grow high-quality monolayer ferromagnet CrBr 3 on a NbSe 2 superconducting substrate. The mirror symmetry is broken at the interface between the different materials, and the...

We have carried out low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS) to probe the magnon excitations in monolayer CrBr 3. We show that the results can be understood in terms of moiré magnons arising from a reconstruction of the magnon dispersion by the moiré pattern formed by the lattice mismatch between CrBr 3 and ...

2023年12月14日 · Here, we demonstrate the effective control of interlayer stacking in exfoliated CrBr 3 via thermally assisted strain engineering. The stable interlayer ferromagnetic (FM), antiferromagnetic (AFM), and FM-AFM coexistent ground states confirmed by the magnetic circular dichroism measurements are realized.

Here, we present the scanning tunneling microscopy and spectroscopy (STM/S) results of CrBr 3 thin and thick flakes exfoliated onto highly ordered pyrolytic graphite (HOPG) surfaces and density functional theory (DFT) calculations to reveal the small energy gap (peak-to-peak energy gap to be 0.57 ± 0.04 eV; or the onset signal energy gap to be ...

CrBr3 is a layered van der Waals material with magnetic ordering down to the 2D limit. So far, the electronic properties of CrBr3 are relatively unexplored. Here, we present the scanning...

2019年8月30日 · Here, we present the scanning tunneling microscopy and spectroscopy (STM/S) results of CrBr 3 thin and thick flakes exfoliated onto pyropytic graphite (HOPG) surfaces and density functional theory (DFT) calculations to reveal the small energy gap (peak-to-peak energy gap to be 0.57 eV ± 0.04 eV; or the onset signal energy gap to be 0.29 ± 0.05 e...

近年来发现的二维磁性材料提供了研究堆叠与磁性的平台，其中 三卤化铬家族 CrX3 （X=Cl, Br, I）引起了研究者的特别关注。 研究表明，CrBr3和CrI3的体材料和单层薄膜都具有 面外易轴的铁磁性，且两者体材料的晶体结构相似。 然而，经由机械剥离而得的CrI3和CrBr3双层膜却呈现出迥然不同的磁耦合特性，前者在多种测量方式下均表现出出人意料的 层间反铁磁耦合，而机械剥离的CrBr3双层膜仍可保持 层间铁磁耦合。 这一反常现象是领域内的一大未解之谜，引起了广泛的 …
