Abstract

We study the electronic structure of EuPtP, which exhibits two first-order valence transitions at T₁ = 247 K and T₂ = 201 K, using angle-resolved photoemission spectroscopy. Below T₂, we observe an energy gap at the crossing point of the bulk Eu 4f and conduction bands. The shape of band dispersions is described by a hybridization-band picture based on the periodic Anderson model. Our results demonstrate the c-f hybridization effect in the low-temperature phase of EuPtP.
