Core and surface structure and magnetic properties of mechano-synthesized LaFeO₃ nanoparticles and their Eu³⁺-doped and Eu³⁺/Cr³⁺-co-doped variants.

ABSTRACT: The core and surface structure, and magnetism of mechano-synthesized LaFeO₃ nanoparticles (30-40 nm), Eu³⁺-doped (La_0.70Eu_0.30FeO₃), and Eu³⁺/Cr³⁺ co-doped (La_0.70Eu_0.30Fe_0.95Cr_0.05O₃) are reported. Doping results in a transition from the O'-type to the O-type distorted structure. Traces of reactants, intermediate phases, and a small amount of Eu²⁺ ions were detected on the surfaces of the nanoparticles. The nanoparticles consist of antiferromagnetic cores flanked by ferromagnetic shells. The Eu³⁺ dopant ions enhance the magnetization values relative to those of the pristine nanoparticles and result in magnetic susceptibilities compatible
