title: Crystalline electric field effects in the filled skutterudite compound PrOs₄P₁₂.
abstract: The filled skutterudite compound PrOs₄P₁₂ was synthesized in single-crystal form using a molten metal flux growth technique. Low-temperature magnetization, specific heat, and electrical resistivity measurements showed no indication of a phase transition down to 0.1 K but had features indicative of crystalline electric field (CEF) effects. Analyses of these features in terms of a cubic CEF suggest a Γ₁ singlet or a Γ₃ doublet ground state separated by 30-50 K from a Γ₅ triplet first excited state.
