FIG. 1.

SEM images of nanoplates: (a) Fe, (b) FeCo, and (c) Co obtained by surfactant-assisted ball milling for 1 h and (d) TEM image of Fe nanoparticles obtained by surfactant-assisted ball milling 20 h.

FIG. 2.

(Color online) XRD patterns of (a) Fe, (b) FeCo, and (c) Co nanoplates and nanoparticles. One-step nanoplates were obtained by wet milling of powders in the presence of surfactants for 1 h. Two-step nanoplates were obtained by first dry-milling starting powders for 20 h followed by wet milling in the presence of surfactants for 20 h. Nanoparticles were obtained from the finest particles floating at the top after the size selection process.

(Color online) Demagnetization curves of Fe nanoplates measured in-plane and out-of-plane direction aligned in magnetic field. Fe nanoplates were obtained by one-step wet milling of starting powders in the presence of surfactants for 1 hr.

FIG. 4.

(Color online) (a) Hysteresis loops of Fe nanoparticles at 300 and 5 K and (b) ZFC and FC curves of Fe nanoparticles measured at the 100 Oe field.
