Spin-polarized Weyl cones and giant anomalous Nernst effect in ferromagnetic Heusler films

Topological Weyl semimetals are promising materials for achieving large anomalous Hall and Nernst effects needed in magnetic and heat flux sensors. Here, the authors visualize the spin-polarized Weyl cone and surface states of ferromagnetic Co2MnGa films, finding a high Nernst thermopower of 6.2 μVK...
