Figure 8From: Preparation of Monodisperse Iron Oxide Nanoparticles via the Synthesis and Decomposition of Iron Fatty Acid ComplexesHysteresis loops of FeO/Fe3O4NPs at temperature of 100 K after zero field cooling (ZFC) and field cooling (FC) in magnetic field up to 1 T. Note that the shifted ZFC loop is the result of a coupling effect at the ferromagnetic and anti-ferromagnetic interfaceBack to article page
