摘要

•La0.8-x□xNa0.2Mn1+xO3-Δ with strong spin-electron coupling has been prepared.•Well-developed crystalline spherical-like nanoparticles contain MnB3+, MnB4+, MnA2+.•Spin-dependent magnetism is observed due to eg-electron localization–delocalization.•Multicomponent nonlinear magnetic system shows complex critical behaviour near TC.•Superparamagnetic contribution of nanoparticles to magnetocaloric effect was found.
