Abstract

In this communication, we are reporting the effect of electron beam (e-beam) irradiation on thermoelectric properties of La_0.8Sr_0.2MnO₃ manganites. The samples were prepared using solid state reaction technique. It is observed that the lattice volume increases with increase in dosage of e-beam. With irradiation an increase in resistivity is observed. For small irradiation dosage, we first observe a decreases in metalinsulator transition temperature T_MI; thereafter T_MI increases with further increase in dosage of irradiation. Both, the resistivity data and thermo-electric power data demonstrate that small polaron hopping model is valid in high temperature region.
