Abstract

The recent bulk studies have revealed the first-order valence phase transition in Ba₂PrRu_1-xIr_xO₆ (0.10≤x≤0.25), while the compounds with x=0 and 1 show antiferromagnetic ordering with T_N=120 and 71 K, respectively. We have carried out zero-field (ZF) muon spin relaxation (μSR) measurements on x=0, 0.1 and 1.0 to investigate the microscopic magnetism. Magnetic ordering has been observed in x=0, 0.1 and 1.0. Furthermore, the ZF-μSR spectra show clear frequency oscillations in x=1.0, indicating a well-defined internal field at the muon site.
