Abstract :
DC susceptibility, specific heat and inelastic neutron scattering measurements have been performed on the metallic pyrochlore compound Pr2Ir2O7. 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 μB oriented along the local 〈111〉 direction of each tetrahedral unit.
