Abstract

We report transverse field muon spin rotation studies of the rare earth pyrochlores Gd₂Ti₂O₇ and Tb₂Ti₂O₇. The paramagnetic shift in the observed precession frequency depends on the local spin susceptibility and probes the contact hyperfine and dipolar fields at the muon site within these materials. The results are compared with measurements of the bulk susceptibility. While no features associated with magnetic ordering are observed down to 0.015 K, hysteretic behavior develops in Tb₂Ti₂O₇ below T = 1 K, likely due to the formation of clusters of ferromagnetically correlated spins.
