Abstract

DC susceptibility, specific heat and inelastic neutron scattering measurements have been performed on the metallic pyrochlore compound Pr ₂Ir₂O₇. No anomalies indicative of a magnetic phase transition were found for temperatures greater than 1.8 K. Our experiments and analysis show that Pr³⁺ ground state is a well-isolated magnetic doublet with Ising-like moments of ∼3.0 μ_B oriented along the local 〈111〉 direction of each tetrahedral unit.
