Markovich, G. Jung, A. Wisniewski, R. Puzniak, I. Fita, Y. Yuzhelevski, D. Mogilyansky, L. Titelman, G. Gorodetsky] Magnetic and transport properties of La0.8Ca0.2MnO3 nanoparticles with average size of 18nm and Curie temperature T C≈231K have been studied. Pronounced irreversibility of magnetization below T irr≈208K has been observed. Studied particles have shown memory effects in zero-field-cooled and field-cooled magnetization. The resistivity has a semiconducting character at 150<T<300K and exhibits relaxation and memory effects below the Curie temperature. The results suggest that superspin-glass features in ensembles of interacting 18nm La0.8Ca0.2MnO3 particles appear along with superferromagnetic-like features.
