Size effects on the Néel temperature of antiferromagnetic NiO nanoparticles
Among all antiferromagnetic transition metal monoxides, NiO presents the highest Néel temperature (TN ∼ 525 K). In this work, the size-dependent reduction of TN in NiO nanoparticles with average diameters (D) ranging from 4 to 9 nm is investigated by neutron diffraction. The scaling law followed by...
