Electrically tunable and reversible magnetoelectric coupling in strained bilayer graphene
Electrically tunable and reversible magnetoelectric coupling in strained bilayer graphene
The valleys in hexagonal two-dimensional systems with broken inversion symmetry carry an intrinsic orbital magnetic moment. Despite this, such systems possess zero net magnetization unless additional symmetries are broken, since the contributions from both valleys cancel. A nonzero net magnetization can be induced through applying both uniaxial strain to break …
