Spin Transport for Spin Diffusion Lengths Comparable to Mean Free Paths

December 15, 2005
Author(s)
David R. Penn, Mark D. Stiles
In perpendicular-transport structures with magnetic and non-magnetic layers, there is a resistance associated with changes in the value of current polarization throughout the structure. Starting from a Boltzmann equation Valet and Fert derived macroscopic

Substitution of Ni for Fe in Superconducting Fe 0.98 Te 0.5 Se 0.5 Depresses the Normal-State Conductivity but not the Magnetic Spectral Weight

… and the low-energy (less than or equal to} 12 meV) magnetic excitations. It is found that, with increasing Ni … are gradually suppressed; in contrast, the low-energy magnetic spectral weight changes little. Comparing with the … contribution to carrier density. The fact that low-energy magnetic spectral weight is not reduced by increased electron …

In-plane Uniaxial Pressure-Induced Out-of-Plane Antiferromagnetic Moment and Critical Fluctuations in BaFe 2 As 2

Steven M. Disseler, Jeffrey W. Lynn, R. F. Jardim, M. S. Torikachvili, E. Granado
The face-centered cubic lattice lattice of Ru 5+ spins in the double perovskite Sr 2YRuO 6 shows a delicate three dimensional antiferromagnetic (AFM) ground state composed of stacked square AFm layers. Inelastic neutron scattering data taken on this state

Electric Field Control of Interfacial Ferromagnetism in CaMnO 3 /CaRuO 3 Heterostructures

July 24, 2015
Author(s)
Alexander J. Grutter, Brian J. Kirby, M. T. Gray, C. L. Flint, U. S. Alaan, Y. Suzuki, Julie A. Borchers
A key milestone for the development of low-power spintronic devices is electric field control of ferromagnetism. To that end, we have probed the electric field dependence of the emergent ferromagntic layer at CaRuO 3/CaMnO 3 interfaces in bilayers

A Numerical Method to Solve the Boltzmann Equation for a Spin Valve

October 1, 2007
Author(s)
J Xiao, A Zangwill, Mark D. Stiles
We present a numerical algorithm to solve the Boltzmann equation for the electron distribution function in magnetic multilayer heterostructures with non-collinear magnetizations. The solution is based on a scattering matrix formalism for layers that are
