Non-equilibrium magnetism in dual spin valves

A. Aziz, O. P. Wessely, M. Ali +4

The field of spin electronics (spintronics) was initiated by the discovery of giant magnetoresistance (GMR) for which Fert[1] and Grunberg[2] were awarded the 2007 Nobel Prize for…

On an inequality concerning the polar derivative of a polynomial

A. Aziz, N. A. Rather

In this paper, we present a correct proof of an -inequality concerning the polar derivative of a polynomial with restricted zeros. We also extend Zygmund's inequality to the p…

Angular dependence of domain wall resistivity in artificial magnetic domain structures

A. Aziz, S. J. Bending, H. G. Roberts +3

We exploit the ability to precisely control the magnetic domain structure of perpendicularly magnetized Pt/Co/Pt trilayers to fabricate artificial domain wall arrays and study thei…

Investigation of artificial domains realised by local gallium focused ion beam (FIB) modification of Pt/Co/Pt trilayer structures

A. Aziz, S. J. Bending, H. Robert +3

We present the results of experimental investigations of magnetic switching and magnetotransport in a new generation of magnetic devices containing artificially patterned domains.…

Spin-orbit strength driven crossover between intrinsic and extrinsic mechanisms of the anomalous Hall effect in epitaxial L1o FePd and FePt

K. M. Seemann, Y. Mokrousov, A. Aziz +8

We determine the composition of intrinsic as well as extrinsic contributions to the anomalous Hall effect (AHE) in the isoelectronic L1o FePd and FePt alloys. We show that the AHE…

Spin-transfer switching and low-field precession in exchange-biased spin valve nano-pillars

M. C. Wu, A. Aziz, D. Morecroft +5

Using a three-dimensional focused-ion beam lithography process we have fabricated nanopillar devices which show spin transfer torque switching at zero external magnetic fields. Und…
