Spin order and fluctuations in the EuAl${}_4$ and EuGa${}_4$ topological antiferromagnets: A $\mu$SR study

X. Y. Zhu, H. Zhang, D. J. Gawryluk +12

We report on systematic muon-spin rotation and relaxation ($\mu$SR) studies of the magnetic properties of EuAl${}_4$ and EuGa${}_4$ single crystals at a microscopic level. Transverse-fie…
