(Color online) STM images of 3–13 ML Fe nanoparticle assembly on . The particle size increases with coverage, and the shape of particles sustains up to 13 ML.
The in-plane MOKE hysteresis loops of 3–13 ML Fe nanoparticles on measured at . After 5 ML, the onset of remanent magnetization is observed.
(Color online) (a) The Kerr remanence shown as a function of temperature for 6.7 ML Fe with 0, 2, and 6 ML Cu capping layers. Significant enhancement is observed. For comparison, of 6.7 ML thin film grown and measured at RT is exhibited. (b) The corresponding STM images and MOKE hysteresis loops.
(Color online) (a) The Kerr remanence shown as a function of temperature for the coverage of 8 ML Co before and after capping of 4 ML Cu. Significant enhancement is observed. (b) and (c) are the STM images before and after capping of 4 ML Cu.
