Structural relaxation effects on interface and transport properties of Fe/MgO(001) tunnel junctions
Xiaobing Feng, O. Bengone, M. Alouani +3
The interface structure of Fe/MgO(100) magnetic tunnel junctions predicted by density functional theory (DFT) depends significantly on the choice of exchange and correlation functi…
Electronic properties of bulk and thin film SrRuO: a search for the metal-insulator transition
James M. Rondinelli, Nuala M. Caffrey, Stefano Sanvito +1
We calculate the properties of the 4 ferromagnet SrRuO in bulk and thin film form with the aim of understanding the experimentally observed metal to insulator transition at…
High yield production of graphene by liquid phase exfoliation of graphite
Y. Hernandez, V. Nicolosi, M. Lotya +16
Graphene is at the centre of nanotechnology research. In order to fully exploit its outstanding properties, a mass production method is necessary. Two main routes are possible: lar…
Quasi-Two-Dimensional Extraordinary Hall Effect
N. Ryzhanova, A. Vedyayev, A. Pertsova +1
Quasi-two-dimensional transport is investigated in a system consisting of one ferromagnetic layer placed between two insulating layers. Using the mechanism of skew-scattering to de…
Nanogaps with very large aspect ratios for electrical measurements
A. Fursina, S. Lee, R. G. S. Sofin +2
For nanoscale electrical characterization and device fabrication it is often desirable to fabricate planar metal electrodes separated by large aspect ratio gaps with interelectrode…
Impurity-Ion pair induced high-temperature ferromagnetism in Co-doped ZnO
C. D. Pemmaraju, R. Hanafin, T. Archer +2
Magnetic 3d-ions doped into wide-gap oxides show signatures of room temperature ferromagnetism, although their concentration is two orders of magnitude smaller than that in convent…
