摘要：

The size effect in electron-doped La0.4Ca0.6MnO3 manganite compound was explored by dc magnetic and X-band electron magnetic resonance measurements in temperature intervals 5-350 K and 5-600 K. The analysis of experimental data verifies the stability of the antiferromagnetic ground state. It is suggested that the stability results from the localized nature of doped electrons in bulk and nanosamples, revealed by fitting the experimental electron paramagnetic resonance parameters to the theoretical models.
