Spin excitations in the candidate Weyl semimetal EuCuAs
Very recently, EuCuAs was proposed as an example of a topological semimetal. Our measurements on Wish show that the Eu magnetic structure is incommensurate with a propagation... -
Ground state magnetic structure of EuCuAs
One of the major themes in solid-state physics is the realisation of exotic types of relativistic electrons which travel at speeds much slower than the speed of light. These...
