Colossal transverse response from non-centrosymmetric kagome ferromagnets
ORAL
Abstract
The interest of the anomalous Hall effect (AHE) and anomalous Nernst effect (ANE) has been renewed since the discoveries of large values of the AHE and ANE due to topologically nontrivial origins, and their potential application to spintronics and efficient energy conversion. Good examples are kagome magnets Mn3Sn and Co2MnGa. Among topological materials, in particular, uranium compounds are one of the best candidates to find large responses of AHE and ANE due to the correlated, flat f-band feature and large spin-orbit coupling that is the key ingredient for topology. However, the study of AHE and ANE for uranium compounds has been very sparse with only a few superconducting exceptions. Here, we will present the giant transverse response from uranium kagome ferromagnets. Our results shed light on the potential of uranium compounds as new spintronic and energy-conversion materials.
