Effect of Anisotropic Hybridization in YbAlB${}_4$ Probed by Linear Dichroism in Core-Level Hard X-ray Photoemission Spectroscopy

Kentaro Kuga, Yuina Kanai, Hidenori Fujiwara +14

We have probed the crystalline electric-field ground states of pure $|J=7/2,J_z=\pm 5/2⟩$ as well as the anisotropic $c$-$f$ hybridization in both valence fluctuating sy…
