The rare earth magnetic perovskite structure LaxSr1-xMnO3 has attracted ren
ewed attention due to their novel physical properties. Nanocrystalline CMR
material LaxSr1-xMnO3 was prepared by the LCS method, and the normal size L
axSr1-xMnO3 was synthesized by the high sintering method. The crystal struc
ture, property and morphology were studied by XRD spectra, FT-IR and TEM. T
he results showed great difference between nanocrystalline and normal sampl
