Exchange coupling and the grain boundary in magnetic nanocomposites
(IEEE, 1997)
The grain boundary phase/material found to be
present in two-phase mechanically alloyed nanocomposites
of Sm2Fel7N3/Fe and NdzFe14B/Fe was characterized
using Mossbauer spectroscopy and magnetization
measurements. The ...
Mass-loss from Red Giants
(2007)
Although much is known about the nature of winds from hot stars and
giants and supergiants with spectral types earlier than K, there is still much
to be learned regarding the mass-loss process in cool, late-type stars. ...
Micromechanical inking and printing of nano-objects using a nanoindenter and electromechanical testing of nanomaterial films
(Trinity College (Dublin, Ireland). School of Physics, 2012)
As research changes focus from traditional silicon based electronic devices towards new materials with exotic capabilities such as carbon nanotubes, nanowires and graphene, the ability to create, pick up and place devices ...
SQUID-detected FMR: Resonance in single crystalline and polycrystalline yttrium iron garnet
(2018)
Here two new techniques for the detection of broadband (100 MHz–20 GHz) ferromagnetic resonance
Here two new techniques for the detection of broadband (100 MHz–20 GHz) ferromagnetic resonance (FMR)/ferrimagnetic resonance ...
Tuning the crystallographic, morphological, optical and electrical properties of ZnO:Al grown by spray pyrolysis
(Elsevier B.V., 2014)
In this contribution the effect of different deposition conditions on the physical properties of ZnO:Al grown by spray pyrolysis is outlined. In particular, it will be shown that the solvent composition affects the ...
Efficient spin injection and giant magnetoresistance in Fe/MoS2/Fe junctions
(2014)
We demonstrate giant magnetoresistance in Fe/MoS2/Fe junctions by means of ab initio transport calculations. We show that junctions incorporating either a monolayer or a bilayer of MoS2 are metallic and that Fe acts as an ...
Spatially resolved self-heating and thermal impedance of laser diodes using CCD-TR imaging
(2021)
The spatial distribution of the surface temperature of single and multi-section slotted semiconductor laser diodes with surface gratings is investigated experimentally with CCDthermoreflectance imaging. The lasers are ...
Magnetic semiconductors for spin electronics
(Trinity College (Dublin, Ireland). School of Physics, 2010)
The development of the relatively new field of spin electronics is based on the possibility of manipulating the spin of the electron through a structure. If one aspect is to develop new device architecture to inject, ...
