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 …

This paper reviews the progress made over the last few years in understanding the
development of perpendicular magnetic tunneling junctions (pMTJs). The material systems …

The low-field magnetization reversal of NiFe∕ Cu∕ Co multilayer mesoscopic elliptical and
circular rings has been investigated via magnetoresistance measurements and …

We suggest a patterned ferromagnetic multibits element for an ultrahigh density magnetic
recording media. The pattern is composed of a circular ferromagnetic disk in contact to four …

We describe the magnetization reversal processes in multilayer elongated Ni 80 Fe 20 (10
nm)/Au (t= 0 to 20 nm)/Co (20 nm)/Si (001) nanorings. For a field applied in-plane along the …

Nanostructured magnetic tunnel junction rings (MTJ) based on CoFeB free layer were
fabricated to investigate the corresponding magnetization reversal processes. The …

The giant magnetoresistance of Ni Fe∕ Cu∕ Co∕ Ir Mn spin valve elliptical rings with 3.2∕
1.9 μ m major/minor diameter and widths of 340–370 nm has been characterized in a …

The ability of magnetic annuli to produce various magnetization configurations make them
attractive for magnetic memory applications. In this study, the authors present …

Microstructured magnetic tunnel junction ring with outer/inner diameter of 2/1 mum has been
fabricated to investigate the angular dependence of magnetoresistance during …

We have investigated the inner diameter dependence of magnetostatic coupling in Fe∕
Au∕ Fe pseudospin valve (PSV) rings by the magneto-optical Kerr effect. Hysteresis loops …
