Negative magnetoresistance in dual spin valve structures with a synthetic antiferromagnetic free layer
(IEEE, 2009)
Giant magnetoresistance (GMR) in spin valves is due to spin-dependent scattering occurring at ferromagnet/normal metal (F/N) interfaces and/or in the ferromagnetic layers. In a spin valve with a typical F/N/F structure ...
Numerical simulations concerning the propagation of protostellar jets
(Trinity College (Dublin, Ireland). School of Physics, 2008)
Point contact Andreev reflection from semimetallic bismuth-The roles of the minority carriers and the large spin-orbit coupling
(2013)
The Point Contact Andreev Reflection (PCAR) technique has been traditionally and predominantly
applied to either the characterisation of superconductors or of spin-polarised metals. The sufficiently
large and slowly ...
Self-assembly of Fe nanocluster arrays on templated surfaces
(2012)
The growth of Fe nanoclusters on the Ge(001) and MoO2/Mo(110) surfaces has been studied using
low-temperature scanning tunneling microscopy (STM) and X-ray magnetic circular dichroism
(XMCD). STM results indicate that ...
Symmetric photonic molecules formed from coupled microspheres
(SPIE, 2008)
Coherent coupling of optical resonances in spherical microcavities results in the formation of so called photonic molecules. The name originates from the analogy to chemical molecules. The coupled optical modes are similar ...
CoTaZr/Pd multilayer with perpendicular magnetic anisotropy
(AIP Publishing, 2013)
We report a novel perpendicularly magnetized thin film [Co91.5 Ta 4.5Zr4/Pd]5 multilayer, which exhibits strong perpendicular magnetic anisotropy when grown on 5 nm of Pd and Ru seed layers. The Pd-seeded multilayer annealed ...
Direct measurement of the contribution of street lighting to satellite observations of nighttime light emissions from urban areas
(2021)
Nighttime light emissions are increasing in most countries worldwide, but which types of lighting are responsible for the increase remains unknown. Also unknown is what fraction of outdoor light emissions and associated ...
Amplitude-mode dynamics of polariton condensates
(2011)
We study the stability of collective amplitude excitations in nonequilibrium polariton condensates. These excitations correspond to renormalized upper polaritons and to the collective amplitude modes of atomic gases and ...
Charge freezing and surface anisotropy on magnetite (100)
(1993)
Scanning tunneling microscope images of the (100) surface of slightly nonstoichiometric magnetite taken at room temperature show static arrays of pairs of Fe2+ ions with short?range order, and a charge fluctuation time ...
Microscopic origin of the 1.3 G0 conductance observed in oxygen-doped silver quantum point contacts
(2014)
Besides the peak at one conductance quantum, G0, two additional features at ∼0.4 G0 and ∼1.3 G0 have been observed in the conductance histograms of silver quantum point contacts at room temperature in ambient conditions. ...
