Connection of Thermopower, Magneto Thermopower with Resistivity and Magnetoresistivity in Nd<sub>(1-x)</sub>Sr<sub>x</sub>MnO<sub>3</sub> and Sm<sub>(1-x)</sub>Sr<sub>x</sub>MnO<sub>3</sub> Manganites
Abstract:An experimental study of thermopower, magneto thermopower, magnetoresistivity and magnetization of Nd (1-x) Sr x MnO 3 and Sm (1-x) Sr x MnO 3 with 0 ≤ х ≤ 0.3 was conducted. A steep rise of thermopower as well as giant values of magneto thermopower and magnetoresistivity were observed near Curie temperature Т С in compounds with 0.15 ≤ х ≤ 0.3. On the other hand, no special features were found in case of х = 0. It has been known that compounds with 0.1 ≤ х ≤ 0.3 consist of ferromagnetic clusters of ferron (ma… Show more
