abstract = {We have investigated different geometries of
two-dimensional (2D) infinite length Ni nanowires of
increasing width using spin density functional theory
calculations. Our simulations demonstrate that the
parallelogram motif is the most stable and structures that
incorporate the parallelogram motif are more stable as
compared to rectangular structures. The wires are conducting
and the conductance channels increase with increasing width.
The wires have a non-linear behavior in the ballistic
anisotropic magnetoresistance ratios (BAMR) with respect to
the magnetization directions. All 2D nanowires as well as Ni
(1 1 1) and Ni (1 0 0) monolayer investigated are
ferromagnetic under the Stoner criterion and exhibit
enhanced magnetic moments as compared to bulk Ni and the
respective Ni monolayers. The easy axis for all nickel
nanowires under investigation is observed to be along the
wire axis. The double rectangular nanowire exhibits a
magnetic anomaly with a smaller magnetic moment when
compared to Ni (1 0 0) monolayer and is the only structure
with an easy axis perpendicular to the wire axis. The Stoner
parameter which has been known to be structure independent
in bulk and surfaces is found to vary with the structure and
the width of the nanowires. The less stable rectangular and
rhombus shaped nanowires have a higher ferromagnetic
strength than parallelogram shaped nanowires.},
