Phase stability, ordering tendencies, and magnetism in single-phase fcc Au-Fe nanoalloys
I. A. Zhuravlev, S. V. Barabash, J. M. An +1
Bulk Au-Fe alloys separate into Au-based fcc and Fe-based bcc phases, but L1 and L1 orderings were reported in single-phase Au-Fe nanoparticles. Motivated by these observat…
First-Principles Theory of Competing Order Types, Phase Separation, and Phonon Scattering in Thermoelectric Pb-Sb-Ag-Te Alloys
S. V. Barabash, V. Ozolins, C. Wolverton
Using a first-principles cluster expansion, we shed light on the solid-state phase diagram and structure of the recently discovered high-performance thermoelectrics, Pb-Ag-Sb-Te al…
Negative Magnetoresistance Produced by Hall Fluctuations in a Ferromagnetic Domain Structure
Sergey V. Barabash, D. Stroud
We present a model for a negative magnetoresistance (MR) that would develop in a material with many ferromagnetic domains even if the individual domains have no magnetoresistance a…
Magnetoresistance of Three-Constituent Composites: Percolation Near a Critical Line
Sergey V. Barabash, David J. Bergman, D. Stroud
Scaling theory, duality symmetry, and numerical simulations of a random network model are used to study the magnetoresistance of a metal/insulator/perfect conductor composite with…
