Description
$SrTm_2O_4$ belongs to the family of $SrLn_2O_4$ (Ln - rare-earth ions), where many unconventional magnetic phenomena have been discovered [1]. However, $SrTm_2O_4$ does not show either long-range or short-range order down to 65mK[2].On the other hand, our muon spin rotation/relaxation (µSR) results show signs of spontaneous magnetic ordering even at near room temperatures with no sign of critical temperature. We conclude with our muon stopping site calculations(µ-DFT) and modeling the impact of muon-induced distortion on the crystal field levels that the quasi-static local field observed with the µSR is due to muon-induced distortions.
