Abstract

A particle size effect to magnetic properties of the mother material of the La-based high-Tc superconducting oxides, La2CuO4 (LCO), was investigated using muon spin relaxation (μSR) measurement in the zero-field condition. A decrease in the Nèel temperature was observed in LCO nanoparticles with a decreasing particle size. The magnetic ground state was found to be an antiferromagnetically ordered state as observed in the bulk state. Two muon sites were confirmed, which showed different temperature dependence of internal fields. It is guessed that oxygen molecules are trapped among nanoparticles, forming a domain-like structure [1].
