6 p, 992.9 KB Effect of asymmetric concentration profile on thermal conductivity in Ge/SiGe superlattices / Hahn, Konstanze R. (Universita degli Studi Di Cagliari. Dipartimento di Fisica) ; Cecchi, Stefano (Paul-Drude-Institut für Festkörperelektronik. Department of Epitaxy) ; Colombo, Luciano (Institut Català de Nanociència i Nanotecnologia)
The effect of the chemical composition in Si/Ge-based superlattices on their thermal conductivity has been investigated using molecular dynamics simulations. Simulation cells of Ge/SiGe superlattices have been generated with different concentration profiles such that the Si concentration follows a step-like, a tooth-saw, a Gaussian, and a gamma-type function in direction of the heat flux.

Departament de Física) ; Fontcuberta, Josep (Institut de Ciència de Materials de Barcelona)
Reversible control of magnetization by electric fields without assistance from a subsidiary magnetic field or electric current could help reduce the power consumption in spintronic devices. When increasing temperature above room temperature, FeRh displays an uncommon antiferromagnetic to ferromagnetic phase transition linked to a unit cell volume expansion. [...]

(Aoyama Gakuin University. Faculty of Science and Engineering)
Using magnetic rare-metals for spintronic devices is facing serious problems for the environmental contamination and the limited material-resource. In contrast, by fabricating ferromagnetic graphene nanopore arrays (FGNPAs) consisting of honeycomb-like array of hexagonal nanopores with hydrogen-terminated zigzag-type atomic structure edges, we reported observation of polarized electron spins spontaneously driven from the pore edge states, resulting in rare-metal-free flat-energy-band ferromagnetism.

Physics Department) ; Klemmer, Timothy J. (Seagate Technology) ; Chantrell, Roy W. (University of York. Department of Physics)
The random substitution of a non-magnetic species instead of Fe atoms in FePt-L1 bulk alloy will permit to tune the magnetic anisotropy energy of this material. We have performed by means of first principles calculations a study of Fe MnPt-L1 (y = 0. [...]
