Abstract

PEROVSKITE compounds (La1-xSmx)0.7 Ca0.3MnO3 0 ≤ x ≤ 0.14 …. were prepared using the double sintering ceramic technique. The measurement of the magnetic susceptibility at different temperatures as a function of the magnetic field intensity showed the change of the state from completely ordered to completely disordered state at T C which shifts to lower value by increasing Sm content. The tolerance factor decreases with increasing Sm concentration. Resistivity measurements indicate the disappearance of the related peaks with increasing Sm content. The large increase in the resistivity below 530K is related to the spin transition of Mn3+ ions from high to low state.
