Abstract
Muon spin precession is observed in the ordered state of antiferromagnetic oxides MnO and V2O3. An anomalous temperature dependence of muon precession frequency and the absence of critical behavior atT N are found in MnO and a hysterisis of the transition temperature is observed in V2O3. These results are explained in terras of the crystal distortion of these materials belowT N.
