A joint publication with Libor Ċ mejkal about the electronic structure of the electrically switchable antiferromagnet CuMnAs has been published in npj Quantum Materials.
They report direct measurements of the electronic structure of single-crystalline thin films of tetragonal CuMnAs using angle-resolved photoemission spectroscopy (ARPES), including Fermi surfaces (FS) and energy-wavevector dispersions. This work underscores the need to control the chemical potential in tetragonal CuMnAs to enable the exploration and exploitation of the Dirac fermions with tunable masses, which are predicted to be above the chemical potential in the present samples.
You can find the publication under npj Quantum Materials volume 8, Article number: 19 (2023).
