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...

| description | 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−1. |
