Linear and nonlinear optical characterisation of self assembled nanostructures
(Trinity College (Dublin, Ireland). School of Physics, 2012)
Spin-polarized electron tunneling across magnetic dielectric
(2005)
This letter deals with a magnetic tunnel junction having spin filtering by a magnetic barrier. We
performed experiments in which a relatively strong external field rotates magnetizations of both
ferromagnetic electrodes ...
Absorption and photoluminescence study of CdS quantum dots: the role of host matrix and nanocrystal size and density
(Materials Research Society, 1999)
Magnetic properties of mechanically-alloyed Sm-Co nanophase hard magnets
(IEEE, 2001)
Highly coercive Sm14Co86 powders were prepared by mechanical alloying with a view to enhance the high temperature magnetic properties by optimizing the annealing conditions. The powders were annealed in quartz tubes with ...
Strategy for detection of electrostatic spin-crossover effect in magnetic molecules
(2013)
Scanning tunneling microscopy (STM) can be used to detect inelastic spin transitions in magnetic nanostructures comprising only a handful of atoms. Here we demonstrate theoretically that STM can uniquely identify the ...
Coronal Mass Ejection Detection using Wavelets, Curvelets and Ridgelets: Applications for Space Weather Monitoring
(2011)
Coronal mass ejections (CMEs) are large-scale eruptions of plasma and magnetic field that can produce adverse space weather at Earth and other locations in the Heliosphere. Due to the intrinsic multiscale nature of features ...
Magnetic order and magnetotransport in half-metallic ferrimagnetic MnyRuxGa thin films
(2021)
The ruthenium content of half-metallic Mn2RuxGa thin films, with a biaxially strained inverse Heusler structure, controls the ferrimagnetism that determines their magnetic and electronic properties. An extensive study of ...
Structural, magnetic and x-ray absorption studies of NdCo 1-xNixO3 (0 ? x ? 0.5)
(2013)
We have systematically investigated the effect of Ni substitution on the structural and magnetic
properties of NdCoO3. Single phase nature and orthorhombic Pbnm structure is confirmed by the
Reitveld refinement of X-ray ...
Investigation of electronic structure and optical properties of organic molecular semiconductor materials by X-ray spectroscopies
(Trinity College (Dublin, Ireland). School of Physics, 2009)
The electronic structure of thin films of several members of the metal phthalocyanine
(MPc) and metal chelate families of organic molecular semiconductors have been
studied using resonant soft x-ray emission spectroscopy, ...
Anisotropic ferromagnetism in substituted zinc oxide
(2004)
The high-temperature ferromagnetism in doped zinc oxide films was discussed. A connection between the electronic structure of (Zn 1-xMx)O and its ferromagnetic properties was found. A new source of magnetism in these oxides, ...
