Abstract: Electrical resistivity, magnetic susceptibility and 151Eu Mössbauer studies have been carried out on La1-xEuxSr0.2MnO3 (0.04≤ x 0.32) compounds. As Eu substitution for La increases, the Curie temperature (TC) decreases from 261 K for x=0.04 to 187 K for x=0.16 along with a decrease in the metal–insulator transition temperature. However, the x=0.32 sample shows an increase in TC to 224 K along with an increase in the metal–insulator transition. The 151Eu Mössbauer studies show that all the Eu are in 3+(4f6,J=0) nonmagnetic state. Broadening of the Mössbauer spectra below TC indicates a transferred magnetic hyperfine field at the Eu site.
