Abstract
The local spin dynamics in the 'paramagnetic' phase of ferromagnetic and ch
arge-ordered Mn perovskites has been investigated by mu(+)SR. A glassy like
spin dynamics is found in the first which has been completely suppressed i
n samples with dominant AF exchange interactions. The observation of a fall
-off in the relaxation rate at To is also discussed in terms of the spin an
d charge dynamics. (C) 1999 Elsevier Science B.V. All rights reserved.
