Abstract
Pure and doped rare-earth-based manganites having mixed valent Mn ions have attracted many researchers and scientists at a global level due to their novel physical properties that are suitable for practical applications. These compounds are known to exhibit metal-to-insulator electronic phase transition along with ferromagnetic-to-paramagnetic transition. In the vicinity of these phase transition temperatures, they exhibit large intrinsic magnetoresistance (MR), which is explained by the Zener double exchange (ZDE) mechanism. Other than ZDE, Jahn–Teller effect is also important to consider for understanding the charge transport properties of manganites. Nanostructured manganites are important specifically because of the low field MR (LFMR) exhibited by them. Grain boundary effects strongly govern the LFMR in nanostructured manganites. However, the grain boundary effects are also responsible for modifying the resistivity, phase transitions, MR behavior, magnetic nature, and other physical properties in different nanostructured mixed valent manganites. Further, the effect of swift heavy ion irradiation on the grain and grain boundary defects density in the nanostructured manganites is also discussed in detail.
