Electronic topological transition of the Lifshitz type and complex magnetic structures in heavy rare-earth metals

摘要

The determining role of the Fermi surface geometry in the formation of long-period magnetic structures in heavy rare-earth metals was considered. It was shown that all these metals are on the verge of electronic topological transition of the Lifshitz type. It was experimentally confirmed that the electronic topological transition induced by elastic deformation results in a change in the type of magnetic ordering. A universal phase diagram "magnetic ordering type-hcp lattice parameters a and c" was established for the rare-earth metals, in good agreement with the results of first-principles calculations.
