Abstract:Transition-metal oxide nanoparticles are relevant for many applications in different areas where their superparamagnetic behavior and low blocking temperature are required. However, they have low magnetic moments, which does not favor their being turned into active actuators. Here, we report a systematical study, within the framework of the density functional theory, of the possibility of promoting a high-spin state in small late-transition-metal oxide nanoparticles through alloying. We investigated all possib… Show more
“…Creating binary nanoparticles by combining elements with different magnetic characteristics is a well-established approach. [32][33][34][35][36][37][38] Alloys combining transition metals (TM) and rare earth (RE) elements exhibit magnetic moments originating from electrons residing in the d and f orbitals, respectively. 39,40 Certain combinations of these elements result in strong antiferromagnetic exchange coupling.…”
