Spintronics is one of the emerging research fields in nanotechnology and has been growing
very rapidly. Studies of spintronics were started after the discovery of giant …

Ferromagnetic metal rings of nanometre range widths and thicknesses exhibit fundamentally
new spin states, switching behaviour and spin dynamics, which can be precisely controlled …

Nickel nanochains assembled with submicrometer-sized hollow spheres were synthesized
through a mild polyol reduction method by using PVP as the soft template. The resulting …

We have proposed a method for controlling the vortex chirality in a squared permalloy dot by
using the circular Oersted field locally induced by flowing a DC current across a small Py/Cu …

The probability laws associated to domain wall depinning under fields and currents have
been studied in NiFe and FePt nanowires. Three basic domain wall depinning processes …

The magnetic properties and magnetoresistance of thin-film circular and elliptical magnetic
rings made from Co, NiFe, NiFe∕ FeMn⁠, and Co∕ Cu∕ NiFe have been explored. Single …

The vortex chirality in an elliptical Co ring spaced 60 nm from a circular ring has been
controlled by magnetostatic interaction. One of the two domain walls (DWs) in the elliptical …

Donut-or ring-shaped Co nanomaterials were successfully synthesized using the polymer-
modified method, by which PVP is used as a surface modifier reagent. The synthesized …

The magnetic and magnetoresistive behaviour of circular and elliptical thin film multilayer
rings is discussed. Rings are particularly interesting because they can adopt several stable …

Controlling the vortex chirality in ferromagnetic nanodots and nanorings has been a topic of
investigation for the last few years. Many control methods have been proposed and it has …
