Variation of Electroresistive Properties of Nanocrystalline Nd0.7Sr0.3MnO3 by Thermobaric Treatment under a Pressure of 9 GPa
Polycrystalline Nd1-xSrxMnO3 was subjected to a thermobaric treatment, that is, a quenching under a high quasihydrostatic pressure of 9 GPa , starting from the temperature 1000 °C. This results in a strong change of the electroresistive and magnetoresistive properties. The changes in the electrical transport might result from the increase of oxygen deficient regions in the boundaries between the nanosized grains.
