Relationship between the Kramers-Kronig relations and negative index of refraction
Mark C. Hickey, Alkim Akyurtlu, Adil-Gerai Kussow
The condition for a negative index of refraction with respect to the vacuum index is established in terms of permittivity and permeability susceptibilities. It is found that the im…
Origin of intrinsic Gilbert damping
M. C. Hickey, J. S. Moodera
The damping of magnetization, represented by the rate at which it relaxes to equilibrium, is successfully modeled as a phenomenological extension in the Landau-Lifschitz-Gilbert eq…
Analytical solution of the equation of motion for a rigid domain wall in a magnetic material with perpendicular anisotropy
M. C. Hickey
This paper reports the solution of the equation of motion for a domain wall in a magnetic material which exhibits high magneto-crystalline anisotropy. Starting from the Landau-Lifs…
Calculated magneto-resistance due to domain walls : the role of impurity scattering
M. C. Hickey
The existing Levy-Zhang approach to constructing the contribution to the resistivity of a magnetic domain wall is explored. The model equations are integrated analytically, giving…
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…
