Unveiling Quantum Superparamagnetism by Interacting Monodomains in Multiferroic Er-Doped Bismuth Ferrate Nanostructured Particles

In the last few years, the quantum superparamagnetic (QSP) phenomenon has been reported in isolated ultrasmall nanoparticles. In this work, a QSP state and superparamagnetic (SP) state in nanostruc...
