Nuclear magnetic resonance and secondary ion mass-spectroscopy have been used to study the surface charge and surface chemical compositions of La₀.₇Sr₀.₃MnO₃ nanoparticles of 12 and 50-100 nm size. It is found that the surface of particles is characterized by an increased content of Sr and Mn ions t...
