摘要：
The directed orientation of ferromagnetic nanowires tethered to spatially controlled regions of a surface is reported. The Figure is a light microscope image of 9 mum-long, two-segment Au/Ni nanowires with a biotinylated An segment tethered to patterned avidin tracks. The aspect ratio of the nickel segments is similar to 50, so the magnetic easy axis is parallel to the wire axis. The nanowires have rotated to be parallel to an applied magnetic field.
