Graphene is composed of a single layer of carbon atoms arranged in a two-dimensional
(2D) honeycomb lattice. It is a fundamental building block for a range of well-known carbon …

When the magnetic order is introduced into topological insulators (TIs), the time-reversal
symmetry (TRS) is broken, and the non-trivial topological surface is driven into a new …

Topological insulators represent a new quantum state of matter which is characterized by
peculiar edge or surface states that show up due to a topological character of the bulk wave …

Recent demonstrations of magnetization switching induced by in-plane current in heavy
metal/ferromagnetic heterostructures (HMFHs) have drawn great attention to spin torques …

We report a nearly ideal quantum anomalous Hall effect in a three-dimensional topological
insulator thin film with ferromagnetic do**. Near zero applied magnetic field we measure …

Symmetry-protected topological crystalline insulators (TCIs) have primarily been
characterized by their gapless boundary states. However, in time-reversal-(T-) invariant …

Electric-field manipulation of magnetic order has proved of both fundamental and
technological importance in spintronic devices. So far, electric-field control of …

The massless Dirac fermions residing on the surface of three-dimensional topological
insulators are protected from backscattering and cannot be localized by disorder, but such …

Two-dimensional MA2Z4 (M= Mo, W, V, Nb, Ta, Ti, Zr, Hf, or Cr; A= Si or Ge; Z= N, P, or As)
is a new lead in the 2D family, because it exhibits versatile properties by tuning the …

Introducing magnetic order in a topological insulator (TI) breaks time-reversal symmetry of
the surface states and can thus yield a variety of interesting physics and promises for novel …
