Effect of sintering temperature on magneto-transport properties of La0.67Ba0.33MnO3/Ba0.7Sr0.3TiO3 composites

Crystallographic direction dependence of electrical-transport, magneto-transport, magnetic and thermal properties of La 0.7 Ca 0.3 MnO 3 single crystal

“…We would like to point out that average A-site ionic radius (<rA>) in La-Ca manganite is substantially lower than that of La-Sr and La-Ba manganites. Therefore due to reduction in <rA>, the eg bandwidth decreases and MR% increases [42][43][44].…”

Influence of BTO phase on structural, magnetic and electrical properties of LCMO

“…The MR originated from the suppression of spin fluctuations, when spins are aligned on application of magnetic field, [4] is known as IMR. Attempts have also been made to increase the MR through the formation of some composites [6][7][8][9]. This grain boundary MR or EMR is generally ascribed to the intergrain tunneling of spin polarized conduction electrons [10].…”

The structure and magnetotransport properties of La2/3Sr1/3MnO3/Ba(La)TiO3 composites

“…An increase in resistivity and an enhancement in low-field magnetoresistance have been observed in these composites. Moreover, piezoelectric BaTiO 3 [8][9][10][11][12] were also introduced into manganites to enhance the magnetoresistance effect. On the one hand, BaTiO 3 is insulator phase and there exists spindependent tunneling and scattering effect.…”
