    Reversible non-volatile electronic switching in a near-room-temperature van der Waals ferromagnet

    Non-volatile phase-change memory devices utilize local heating to toggle between crystalline and amorphous states with distinct electrical properties. Expanding on this kind of switching to two topologically d...

    Observation of fractionally quantized anomalous Hall effect

    The integer quantum anomalous Hall (QAH) effect is a lattice analogue of the quantum Hall effect at zero magnetic field1–3. This phenomenon occurs in systems with topologically non-trivial bands and spontaneous t...

    Layer Hall effect in a 2D topological axion antiferromagnet

    Whereas ferromagnets have been known and used for millennia, antiferromagnets were only discovered in the 1930s1. At large scale, because of the absence of global magnetization, antiferromagnets may seem to behav...

    A van der Waals antiferromagnetic topological insulator with weak interlayer magnetic coupling

    Magnetic topological insulators (TI) provide an important material platform to explore quantum phenomena such as quantized anomalous Hall effect and Majorana modes, etc. Their successful material realization i...
