A study of single-phase La0.9Pb0.1MnO3 compositions is presented. The temperature dependence
of the EPR line intensity and resistivity evidence a spin-lattice interaction in the paramagnetic region near
the Curie point. In the high temperature region a spin-spin interaction is dominant. ?? 2004 WILEY-VCH
