Abstract
Muon relaxation techniques are used in a comparative study of charge-ordere d Mn perovskites with commensurate (Pr1/2Ca1/2MnO3) and incommensurate (Pr2 /3Ca1/3MnO3) charge concentration. A strong modification of the spin dynami cs is observed in Pr2/3Ca1/3MnO3 for which the ferromagnetic correlations a re the dominant relaxation mechanism. (C) 2000 Elsevier Science B.V.
