Unusual magnetotransport in twisted bilayer graphene
Joe Finney, Aaron L. Sharpe, Eli J. Fox +10
We present transport measurements of bilayer graphene with 1.38° interlayer twist and apparent additional alignment to its hexagonal boron nitride cladding. As with other devices w…
Directional ballistic transport in the two-dimensional metal PdCoO2
Maja D. Bachmann, Aaron L. Sharpe, Arthur W. Barnard +8
In an idealized infinite crystal, the material properties are constrained by the symmetries of its unit cell. Naturally, the point-group symmetry is broken by the sample shape of a…
Evidence of orbital ferromagnetism in twisted bilayer graphene aligned to hexagonal boron nitride
Aaron L. Sharpe, Eli J. Fox, Arthur W. Barnard +5
We have previously reported ferromagnetism evinced by a large hysteretic anomalous Hall effect in twisted bilayer graphene (tBLG). Subsequent measurements of a quantized Hall resis…
