Abstract

Abstract Transport and magnetic properties of LaMnO3+δ nanoparticles with average size of 18 nm have been investigated. The ensemble of nanoparticles exhibits a paramagnetic to ferromagnetic (FM) transition at TC∼246 K, while the spontaneous magnetization disappears at T≈270 K. It was found that the blocking temperature lies slightly below TC. The temperature dependence of the resistivity shows a metal–insulator transition at T≈192 K and low-temperature upturn at T
