    • Abstract

       

      In this article, we provide an overview of the basic conceptsof novel topological materials. This new class of materialsdeveloped by combining the Weyl/Dirac fermionic electronstates and magnetism, provide a materials-science platformto test predictions of the laws of topological physics. Owingto their dissipationless transport, these materials hold highpromises for technological applications in quantum computingand spintronics devices.
