M?_ssbauer spectrometry of A2FeMoO6 (A =Ca, Sr, Ba): Search for antiphase domains
(American Physical Society, 2001)M?_ssbauer spectrometry was carried out in the range of temperature from 4 K to well above the Curie temperature on polycrystalline ceramics of A2FeMoO6 (A=Ca,Sr,Ba). A secondary component in all the paramagnetic or ... -
Machine-learning approach for quantified resolvability enhancement of low-dose STEM data
(2023)High-resolution electron microscopy is achievable only when a high electron dose is employed, a practice that may cause damage to the specimen and, in general, affects the observation. This drawback sets some limitations ... -
Magnesium, nitrogen codoped Cr2O3: A p-type transparent conducting oxide
(2011)A p-type transparent conductive oxide (TCO) was synthesised by codoping of poorly conducting chromium oxide (Cr2O3) with magnesium and nitrogen. We demonstrated that the codoping produced a TCO with good figure of merit ... -
Magnetic activity and hot Jupiters of young Suns: the weak-line T Tauri stars V819 Tau and V830 Tau
(2015)We report results of a spectropolarimetric and photometric monitoring of the weak-line T Tauri stars (wTTSs) V819 Tau and V830 Tau within the MaTYSSE programme, involving the ESPaDOnS spectropolarimeter at the Canada-France-Hawaii ... -
Magnetic and Electronic Phenomena in Oxide Interfaces, Thin Films and Heterostructures
The miniaturisation and reduction of power consumption in modern integrated circuitry and active compo- nents such as sensors and memory demands the development of novel materials. These materials must not only have ... -
Magnetic and transport properties of epitaxial stepped Fe3O4(100) thin films
(2014)We investigate the magnetic and transport properties of epitaxial stepped Fe3O4 thin films grown with different thicknesses. Magnetization measurements suggest that the steps induce additional anisotropy, which has an easy ... -
Magnetic and transport properties of magnetite based nanostructures
(Trinity College (Dublin, Ireland). School of Physics, 2009)In this thesis, we investigate the magnetic and transport properties of magnetite based nanostructures. We in particular investigate the magnetization and surface Verwey transition of magnetite thin film, interlayer ... -
Magnetic barcodes in molecular medicine
(Trinity College (Dublin, Ireland). School of Physics, 2010)The need for faster and more sensitive diagnostic systems for the early detection of many life-threatening diseases is the driving force behind the work in this thesis. A lab-on-a-chip prototype device incorporating a ... -
Magnetic control over the fractal dimension of supramolecular rod networks
(2021)Controlling supramolecular polymerization is of fundamental importance to create advanced materials and devices. Here we show that the thermodynamic equilibrium of Gd3+-bearing supramolecular rod networks is shifted ... -
Magnetic coupling in Co Cr2 O4 and Mn Cr2 O4: An LSDA+U study
(American Physical Society, 2007)We present a first principles LSDA+U study of the magnetic coupling constants in the spinel magnets CoCr2O4 and MnCr2O4. Our calculated coupling constants highlight the possible importance of AA interactions in spinel ...
