Altermagnetism Research at the German-Ukrainian Center for Quantum Materials

This presentation highlights the German-Ukrainian Center for Quantum Materials (GU-QuMat) and focuses on one of its research directions: altermagnets. A significant number of altermagnetic materials have been predicted, with notable distinctions between their metallic and ionic forms. While metallic altermagnets are relatively rare, they exhibit intriguing properties. Ionic altermagnets, on the other hand, often feature large spin splittings. Predicted properties of altermagnets span a broad range, including spin-charge and spin-heat transport, piezomagnetism, anomalous Hall conductivity, Weyl semimetallicity, magnetic domain structures, and applications in curved nano-membranes. These findings underscore the rich potential of altermagnets for advancing quantum material science.
