Local-structure origins of the sustained Curie temperature in (Ba,Ca)TiO3 ferroelectrics
Igor Levin, Victor Krayzman, and Joseph C. Woicik
While the lattice volume in the solid-solution Ba1−xCaxTiO3 decreases with increasing x, the Curie temperature remains unaffected, in contrast to Ba1−xSrxTiO3. We have determined the origin of this phenomenon by comparing the local structures in (Ba,Ca)TiO3 and (Ba,Sr)TiO3.
Tunable giant magnetic anisotropy in amorphous SmCo thin films
F. Magnus, R. Moubah, A. H. Roos, A. Kruk, V. Kapaklis, T. Hase, B. Hjörvarsson, and G. Andersson
SmCo thin films have been grown by magnetron sputtering at room temperature with a composition of 2–35 at. % Sm. Films with 5 at. % or higher Sm are amorphous and smooth
Improving the intrinsic cut-off frequency of gate-all-around quantum-wire transistors without channel length scaling
A. Benali, F. L. Traversa, G. Albareda, M. Aghoutane, and X. Oriols
Progress in high-frequency transistors is based on reducing electron transit time, either by scaling their lengths or by introducing materials with higher electron mobility. For gate-all-around quantum-wire transistors with lateral dimensions similar or smaller than their length, a careful analysis of the displacement current reveals that a time shorter than the transit time controls their high-frequency performance.
Dexterous manipulation of microparticles using Bessel-function acoustic pressure fields
Charles R. P. Courtney, Bruce W. Drinkwater, Christine E. M. Demore, Sandy Cochran, Alon Grinenko, and Paul D. Wilcox
The authors show that Bessel-function acoustic pressure fields can be used to trap and controllably position microparticles. A circular, 16-element ultrasound array generates and manipulates an acoustic field within a chamber, trapping microparticles and agglomerates.
Tuning magnetic anisotropy in (001) oriented L10 (Fe1−xCux)55Pt45 films
Dustin A. Gilbert, Liang-Wei Wang, Timothy J. Klemmer, Jan-Ulrich Thiele, Chih-Huang Lai, and Kai Liu
The authors have achieved (001) oriented L10 (Fe1−xCux)55Pt45 thin films, with magnetic anisotropy up to 3.6 × 107 erg/cm3, using atomic-scale multilayer sputtering and post annealing at 400 °C for 10 s. By fixing the Pt concentration, structure and magnetic properties are systematically tuned by the Cu addition.
