Abstract

Using the technique of penetration of electromagnetic waves through the bulk samples of La0.60Er0.07Ba0.33MnO3 manganite, it is shown that in this class of strongly correlated materials the local dynamic magnetic ordering is preserved at the temperature by 66 K above the Curie temperature where the static long-range magnetic order is absent. In this temperature range the dynamic magnetic permeability exceeds unity and is frequency dependent. The average lifetime of local ordered states is estimated.
