Onion-type complexation based on carbon nanorings and a buckminsterfullerene.

Manipulation of a magnetic state by a spin-polarized current is one of the exciting topics in solid state physics. We succeeded in driving a magnetic domain wall (DW) in magnetic nanowire by an electric current flowing through the wire. Figure 1 (a) shows a schematic illustration of a top view of a sample. One end of the L-shaped wire is connected to a diamond shaped pad which acts as a DW injector. A single DW can be introduced from the DW injector, and it stops in the hatched area. Figure 1 (b)-(f) shows the realspace observation of the current-driven DW motion by using the magnetic force microscopy (MFM). These are successive MFM images with one pulsed-current applied between Real-Space Observation of Current-Driven Domain Wall Motion in Submicron Magnetic Wires YAMAGUCHI Akinobu and NASU Saburo (Graduate School of Engineering Sience)
