Growth and magnetism of self-organized arrays of Fe(110) wires formed by deposition on kinetically grooved W(110)

چکیده
Homoepitaxy of W(110) and Mo(110) is performed in a kinetically-limited regime to yield a nanotemplate in the form of a uniaxial array of hills and grooves aligned along the [001] direction. The topography and organization of the grooves were studied with RHEED and STM. The nanofacets, of type {210}, are tilted ∼ 18◦ away from (110). The lateral period could be varied from 4 to 12 nm by tuning the deposition temperature. Magnetic nanowires were formed in the grooves by deposition of Fe at 150◦C on such templates. Fe/W wires display an easy axis along [001] and a mean blocking temperature TB ≈ 100K.

متن کاملTunable magnetic properties of arrays of Fe(110) nanowires grown on kinetically-grooved W(110) self-organized templates
We report a detailed magnetic study of a new type of self-organized nanowires disclosed briefly previously [B. Borca et al., Appl. Phys. Lett. 90, 142507 (2007)]. The templates, prepared on sapphire wafers in a kinetically-limited regime, consist of uniaxially-grooved W(110) surfaces, with a lateral period here tuned to 15 nm. Fe deposition leads to the formation of (110) 7 nm-wide wires locate...

We demonstrate the kinetically controlled growth of one-dimensional Co nanomagnets with a high lateral order on a nanopatterned Ag(110) surface. First, self-organized Si nanoribbons are formed upon submonolayer condensation of Si on the anisotropic Ag(110) surface. Depending on the growth temperature, individual or regular arrays (with a pitch of 2 nm) of Si nanoribbons can be grown. Next, the ...
متن کاملKinetically driven self-organization during hydrogen-assisted MBE growth on GaAs(110)
Self-organized growth of GaAs on (110) substrates vicinal to (111)A by hydrogen-assisted molecular beam epitaxy (H-MBE) has been studied for different kinetic regimes using atomic force microscopy (AFM). When GaAs growth is limited by kinetics of adatom incorporation to steps, the presence of chemisorbed H on the surface after oxide removal promotes the incorporation of adatoms to steps from th...
متن کاملKinetic self-organization of trenched templates for the fabrication of versatile ferromagnetic nanowires
We have self-organized versatile magnetic nanowires, i.e. with variable period and adjustable magnetic anisotropy energy (MAE). First, using the kinetic roughening of W(110) uniaxial templates of trenches were grown on commercial Sapphire wafers. Unlike most templates used for self-organization, those have a variable period, 4-12 nm are demonstrated here. Fe deposition then results in the forma...
