Restored quantum size effects of Pb overlayers at high coverages
(APS, 2007-04-10)
Abnormally large stability of Pb nanostructures grown on metallic or semiconductor substrates has been observed even for heights of about 30 monolayers. Using both density-functional theory calculations and analytical ...
Temperature dependence of spin diffusion length and spin Hall angle in Au and Pt
(Americal Physical Society, 2015-01-05)
We have studied the spin transport and the spin Hall effect as a function of temperature for platinum (Pt) and gold (Au) in lateral spin valve structures. First, by using the spin absorption technique, we extract the spin ...
Temperature dependence of spin polarization in ferromagnetic metals using lateral spin valves
(Americal Physical Society, 2013-11-15)
Spin injection properties of ferromagnetic metals are studied and are compared by using highly reproducible cobalt/copper and permalloy/copper lateral spin valves (LSVs) with transparent contacts, fabricated with a careful ...
Lattice dynamics and in-plane antiferromagnetism in MnxZn1−xPS3 across the entire composition range
(American Physical Society, 2023-03-16)
Alloyed MnxZn1−xPS3 samples have been grown covering the whole compositional range and studied by means of Raman spectroscopy at temperatures from 4 to 850 K. Our results, supported by superconducting quantum interference ...
Unravelling the electrochemical activation and the reaction mechanism of maricite-NaFePO4 using multimodal operando techniques
(RSC, 2023-08-23)
The electrochemical properties of maricite NaFePO4 can be activated by ball milling with carbon. The origin of such activation is still unclear, as this material does not exhibit apparent open channels for Na+diffusion. ...
Sensitiveness of the ratio between monovacancy and bulk positron lifetimes to the approximations used in the calculations: Periodic behaviour
(Elsevier, 2012-05-09)
Positron lifetimes have been calculated in bulk and monovacancies for most of the elements of the periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the electronic structure ...
Simultaneous detection of the spin-Hall magnetoresistance and the spin-Seebeck effect in platinum and tantalum on yttrium iron garnet
(Americal Physical Society, 2014-11-26)
The spin-Seebeck effect (SSE) in platinum (Pt) and tantalum (Ta) on yttrium iron garnet has been investigated by both externally heating the sample (using an on-chip Pt heater on top of the device) and by current-induced ...
Positron lifetime calculation of the elements of the periodic table
(IOP, 2007-04-10)
Theoretical positron lifetime values have been calculated systematically for most of the elements of the periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the electronic ...
Optimal strategies of deployment of far offshore co-located wind-wave energy farms
(Elsevier, 2022-01-01)
[EN] The most profitable offshore energy resources are usually found away from the coast. Nevertheless, the accessibility and grid integration in those areas are more complicated. To avoid this problematic, large scale ...
Floating wind turbine energy and fatigue loads estimation according to climate period scaled wind and waves
(Elsevier, 2022-11)
Offshore wind power is one of the fastest-growing renewable energy sources, as it is expected to play a major role in the transition towards sustainability and net zero emissions. Despite its potential, the interaction of ...
