Contribution

First muon spin relaxation study comparing LaTiO3 and YTiO3, identifying muon stopping sites and confirming magnetic structures with prior neutron data.

Findings

Observed oscillations indicating 3D magnetic order

Identified two magnetically inequivalent muon sites

Results align with previous neutron diffraction studies

Abstract

We report muon spin relaxation measurements on two Ti3+ containing perovskites, LaTiO3 and YTiO3, which display long range magnetic order at low temperature. For both materials, oscillations in the time-dependence of the muon polarization are observed which are consistent with three-dimensional magnetic order. From our data we identify two magnetically inequivalent muon stopping sites. The muon spin relaxation results are compared with the magnetic structures of these compounds previously derived from neutron diffraction and muon spin relaxation studies on structurally similar compounds.
