Unconventional magnetism and electronic transport in magnetic Weyl semimetals RAlX
ORAL
Abstract
We study the electronic and magnetic properties in magnetic Weyl semimetals RGeX, where R denotes rare-earth elements and X=Si/Ge. First, we find that by virtue of the strong spin-orbit coupling the magnetic moments of the rare earth ions are ordered in an unconventional manner, which can be further controlled by external magnetic fields. On the other hand, the conduction electrons near the Fermi surface host both type-\I\ and type-\II\ Weyl nodes. Such topological conduction electrons are coupled to the local magnetic moments through Kondo couplings, which allow for the control of the Weyl nodes by manipulating the magnetic moments, leading to anomalous electronic transport behavior.
