Fig. 3From: The Boundary Between Volume and Surface-Driven Magnetic Properties in Spinel Iron Oxide Nanoparticlesa A magnification at low field of the M versus H curves measured at 5 K for all samples with b the full range of measurement. The size dependence of coercive field (µ0HC), anisotropy field (µ0Ha), and the high-field susceptibility (dM/dµ0H) measured at 5 T are reported in panels c, d, and e, respectively, with lines used as a guide to the eyeBack to article page
