Magnetic properties of Mn doped ZnO tetrapod structures
ZnO tetrapod nanostructures were prepared by evaporating Zn metal under humid argon flow. After the fabrication, Mn diffusion doping was performed at two different temperatures (600 and 800 °C). T...

Uniaxial magnetic anisotropy tuned by nanoscale ripple formation: Ion-sculpting of Co/Cu(001) thin films
We have investigated the growth of surface nanostructures on a Co/Cu(001) film and the growth of Co films on a nanostructured Cu(001) substrate as well as the effect of nanoscale pattern formation on ...

We report a universal dependence of switching field of patterned magnetic nanolines as a function of the linewidth for Co and NiFe films of various thicknesses. This dependence is shown to be consistent with a nucleation picture in which the magnetization reversal is controlled only by a small nucleus equivalent to a particle with an aspect ratio of 1.25, which spreads across the width of the nanoline. Micromagnetic simulation, taking into account of the edge roughness, agrees well with the observed results. ©2004 American Institute of Physics.
