FIG. 1.

X-ray diffraction pattern for FeO nanoparticles with 〈D〉 = 40 nm.

FIG. 2.

FeO nanoparticles in-phase susceptibility curves for temperature ranging from 5 to 150 K. At the inset, out-phase susceptibility curves; the peak shifting with frequency is pointed.

Image of FIG. 3.
FIG. 3.

Activation energy, E, dependence on frequency. The inset shows the in-phase susceptibility curves with their corresponding fittings.

Image of FIG. 4.
FIG. 4.

Hysteresis loops for FeO nanoparticles at different temperatures. At the inset, a zoom to the coercivity values, where a big decrease on coercivity confirmed the spin-glass transition.

Tables
