Weak localization and universal conductance fluctuations in large area twisted bilayer graphene
Spenser Talkington, Debarghya Mallick, An-Hsi Chen +7
We study diffusive magnetotransport in highly p-doped large area twisted bilayer graphene in 1°, 7°, 9° and 20° samples. We report weak localization in twisted bilayer graphene…
Magnetic Imaging of Macroscopic Spin Chirality Flipping
H. Miao, G. Fabbris, J. Bouaziz +12
Chirality is a fundamental organizing principle of correlated and topological states. In quantum magnets, chirality arises from the geometric twisting of spins and serves as an eme…
Intrinsic Even-Odd Thickness-Driven Anomalous Hall in Epitaxial MnBi2Te4 Thin Films
Debarghya Mallick, Simon Kim, An-Hsi Chen +12
We demonstrate precise control of magnetism in MnBi2Te4 thin films through careful synthesis by molecular beam epitaxy, achieving minimal defects and accurate layer thickness contr…
Active Learning for Tractable and Reproducible Pulsed Laser Deposition
Jackson S. Bentley, Christopher Rouleau, Ilia N. Ivanov +8
This paper shows how data-driven machine learning approaches can improve growth control, reproducibility, and physical insight in the pulsed laser deposition (PLD) growth of correl…
Strain patterning of flexomagnetism
Tamalika Samanta, Zachary T. LaDuca, An-Hsi Chen +15
Flexomagnetism, the coupling of magnetic ordering to strain gradients, provides access to novel symmetry-broken magnetic phases that cannot be accessed via uniform strain. However,…
Nucleation and Antiphase Twin Control in BiSe via Step-Terminated AlO Substrates
Alessandro R. Mazza, Jia Shi, Gabriel A. Vázquez-Lizardi +18
The epitaxial synthesis of high-quality 2D layered materials is an essential driver of both fundamental physics studies and technological applications. BiSe, a prototypical…
