Abstract

Electronic state evolution in the metal–nonmetal transition of PrRu<SUB>4</SUB>P<SUB>12</SUB> has been studied by X-ray and polarized neutron diffraction experiments. It has been revealed that, in the low-temperature nonmetallic phase, two inequivalent crystal-field (CF) schemes of Pr<SUP>3+</SUP> 4<I>f</I><SUP>2</SUP> electrons with Γ<SUB>1</SUB> and Γ<SUB>4</SUB><SUP>(2)</SUP> ground states are located at Pr1 and Pr2 sites forming the bcc unit cell surrounded by the smaller and larger cubic Ru-ion sublattices, respectively. This modulated electronic state can be explained by the <I>p</I>–<I>f</I> hybridization mechanism taking two intermediate states of 4<I>f</I><SUP>1</SUP> and 4<I>f</I><SUP>3</SUP>. The <I>p</I>–<I>f</I> hybridization effect plays an important role in the electronic energy gain in the metal–nonmetal transition originated from the Fermi surface nesting.
