Strong in-plane anisotropy in the electronic structure of fixed-valence β − LuAlB 4
The origin of intrinsic quantum criticality in the heavy-fermion superconductor β-YbAlB4 has been attributed to strong Yb valence fluctuations and its peculiar crystal structure. Here, we assess these contributions individually by studying the isostructural but fixed-valence compound β-LuAlB4. Quant...
