Oxide template for self-assembling arrays of metal nanoclusters
(2006)
We demonstrate that ordered arrays of metal clusters of a few nanometers in size can be fabricated by self-assembly on a range of oxide nanotemplates. Two systems were chosen, FeO/Pt(111) and Fe3O4, having in common a ...
Crystal Fields in Nd2Fe14B
(American Physical Society, 1984)
The leading terms in the crystal field at both rare-earth sites in the new permanent magnet alloy Nd2Fe14B are B20 and B22s. The sign of B20 explains the variation of the anisotropy constant K1 reported by Sagawa et al. ...
Conducting channel at the LaAlO3/SrTiO3 interface
(2013)
Localization of electrons in the two-dimensional electron gas at the LaAlO3/SrTiO3 interface is investigated by varying the channel thickness in order to establish the nature of the conducting channel. Layers of SrTiO3 ...
Computational modelling of novel permanent magnetic designs
(Trinity College (Dublin, Ireland). School of Physics, 2005)
Moderm permanent magnetic materials provide unique design opportunities as their
low susceptibility makes them effectively transparent to external magnetic fields. This
also simplifies the calculation of magnetic fields ...
Spin polarization and magnetotransport properties of systematically disordered Fe60Al40 thin films
(2021)
We investigate the evolution of spin polarization, spontaneous Hall angle (SHA), saturation magnetization,
and Curie temperature of B2-ordered Fe 60 Al 40 thin films under varying antisite disorder, induced by ...
Surface Studies of Niobium Oxides
(Trinity College Dublin. School of Physics. Discipline of Physics, 2024)
In this thesis, two important niobium-oxygen systems are studied. The first system is the NbO "nanocrystal" termination of Nb(110). A new model to explain this structure based on a monolayer of oxygen covering the surface ...
Spatial correlations in polydisperse, frictionless, two-dimensional packings.
(2011)
We investigate next-nearest-neighbor correlations of the contact number in simulations of polydisperse, frictionless packings in two dimensions. We find that disks with few contacting neighbors are predominantly in contact ...
Tuning behaviour of slotted vernier widely tunable lasers
(2019)
A detailed thermo-optic model combining the 1D transfer matrix method and a 3D finite element method is developed and used to simulate a widely tunable vernier laser based on surface etched slots. The model is used to ...
Ultra-soft magnetic Co-Fe-B-Si-Nb amorphous alloys for high frequency power applications
(2018)
With the continuous shrinkage of the footprint of inductors and transformers in modern power supplies, higher flux, while still low-loss metallic replacements of traditional ferrite materials are becoming an intriguing ...
