Abstract

A discontinuous change of muon-spin precession frequencies in CaV ₃O₇ is observed at T∼0.2K, indicating a possible spin reorientation. Our results suggest that CaV₃O₇ possesses the identical spin direction as isostructural SrV₃O₇ below ∼0.2 K, although the spin directions in the two compounds are different at higher temperatures as determined by elastic neutron scattering.
