MFM Images Obtained by Electrodeposited Magnetic Tips.

Magnetic force microscopy using fabricated cobalt-coated carbon nanotubes probes

Magnetic force microscope ( MFM ) is a powerful technique for mapping the magnetic force gradient above the sample surface. Herein, single-wall carbon nanotubes (SWCNT) were used to fabricate MFM probe by dielectrophoresis method which is a reproducible and cost-effective technique. The effect of induced voltage on the deposition manner of carbon nanotubes (CNT) on the atomic force microscope (...

Atomic row doubling in the STM images of Cu(014)-O obtained with MnNi tips.

We report on scanning tunneling microscopy studies of the Cu(014)-O surface using MnNi tips. Remarkably, the results show a regular apparent doubling of surface atomic rows in the {110} direction. A qualitative explanation of this feature based on tight binding and density functional theory calculations of the electronic structure of the tip is presented. Double imaging of the same atom by diff...

Evolution of the Magnetic Moment Distribution of Arrays of Nanowires Studied by Mfm

The development of high-density magnetic storage media based on magnetic nanostructures is currently attracting a great interest. The self-organization techniques reveal as one of the most efficient methods to obtain nanostructures in a large scale. Among these techniques (growth of islands, ion irradiation, particles assembly, etc) we have used the selective electrodeposition of metals to fabr...
