Electroresistive Effect in Slightly Oxygen Deficient Nd_0.7Sr_0.3MnO_3‐δ Ceramic.

Abstract

0.3 MnO 3-δ Ceramic. -Resistance measurements reveal a strong electroresistive effect in the title ceramic which behaves equivalent to the well-known magnetoresistive effect and which apparently involves both the higher insulating grain boundaries as well as parts of the domain volume. The electroresistive effect increases dramatically with δ. -(MORCHSHAKOV, V.; YANG, C. P.; TROYANCHUK, I. O.; BAERNER*, K.;
