Adsorption geometry of individual fullerene on Si surface at room-temperature
Xinli Du, Feng Chen, Xiu Chen, Xianxin Wu, Yingxiang Cai, Xiaoqing Liu, and Li Wang

Statistical analysis of scanning tunneling microscopy images demonstrate that fullerene molecules prefer to adsorb on five specific sites: corner hole, the middle of the faulted and unfaulted parts, and the top of the rest atoms within the faulted and unfaulted parts. By combining these internal fine structures with theoretical simulations, the molecular orientations at each of the adsorption sites can be unambiguously determined.

Enhancement of the spin pumping efficiency by spin wave mode selection
C. W. Sandweg, Y. Kajiwara, K. Ando, E. Saitoh, and B. Hillebrands

Spin pumping is the generation of spin currents from magnetization precession. Standing spin waves drive spin pumping into a platinum layer, which is converted into a detectable voltage due to the inverse spin-Hall effect. The results suggest that the use of higher-mode surface spin waves allows for the fabrication of an efficient spin-current injector.

Reduction in reset current of unipolar NiO-based resistive switching through nickel interfacial layer
Hyung Dong Lee and Yoshio Nishi

The role of interface between electrode and NiO on switching characteristics has been investigated for unipolar NiO-based resistive switching. A model describing the reduction of reset current mechanism was derived from the combination effect of oxygen vacancy formation/migration and the interfacial oxide layer at cathodic electrode.
