Study of in-plane magnetic anisotropy of ultrathin epitaxial Fe films grown on vicinal Mo(110) surface
(2004)
In situ surface magneto-optical Kerr effect was used in conjunction with scanning tunneling microscopy and low-energy electron diffraction to study the in-plane magnetic anisotropy of ultrathin Fe films on a vicinal Mo(110) ...
Gamma Ray Bursts : probing burst environments in high redshift galaxies
(Trinity College (Dublin, Ireland). School of Physics, 2008)
First discovered in the late 1960s, Gamma Ray Bursts have remained something of a cosmic
mystery for almost four decades. It has only been quite recently that the nature of these phenomena is beginning to be understood. ...
Ab initio electron theory for magnetism in Fe: Pressure dependence of spin-wave energies, exchange parameters, and Curie temperature
(American Physical Society, 2003)
The spin-wave spectra for bcc Fe at various lattice constants are calculated by the ab initio density functional electron theory for various lattice constants, and the exchange parameters of a Heisenberg model are determined ...
Magnetic investigations of Mn-based and Mn-free potential half metals
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
This thesis is concerned with an unusual category of magnetically ordered material, the zero moments ferrimagnetic half metal, which has potential for applications in thin film memory and logic devices. The materials are ...
Exponential behavior of the interlayer exchange coupling across nonmagnetic metallic superlattices
(1998)
It is shown that the coupling between magnetic layers separated by nonmagnetic metallic superlattices can decay exponentially as a function of the spacer thickness N, as opposed to the usual N-2 decay. This effect is due ...
Characterising Pulsars with Low-Frequency Software Telescopes
(Trinity College Dublin. School of Physics. Discipline of Physics, 2024)
Pulsars are a class of rapidly rotating neutron stars that periodically provide detectable emission in the direction of the Earth, where it can be detected by telescopes across the electromagnetic spectrum. These husks of ...
High-pressure Raman spectroscopy of graphene
(2009)
In situ high-pressure Raman spectroscopy is used to study monolayer, bilayer, and few-layer graphene
samples supported on silicon in a diamond anvil cell to 3.5 GPa. The results show that monolayer graphene
adheres to ...
The high-throughput highway to computational materials design
(2013)
High-throughput computational materials design is an emerging area of materials science. By combining advanced thermodynamic and electronic-structure methods with intelligent data mining and database construction, and ...
