Abstract
The Nd-Mn exchange interaction in Nd0.7Sr0.3MnO 3 is considered by studying its influence on the 55Mn spin-echo NMR lineshape and spin-spin relaxation time. It is seen that the interaction is of considerable strength well above the Ndspin ordering temperature (≈20K), with a significant influence on the Mn (electron) spin dynamics. © IOP Publishing Ltd.
