Spin wave dispersion of ultra-low damping hematite ( α−Fe2O3 ) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Low magnetic damping and high group velocity of spin waves (SWs) or magnons are two crucial parameters for functional magnonic devices. Magnonics research on signal processing and wave-based computation at GHz frequencies focused on the artificial ferrimag ...

Zenodo2023Broadband spectroscopy and inelastic light scattering on the canted antiferromagnet hematite for antiferromagnetic magnonics
Collective spin excitations propagating in magnetically ordered materials are called spin waves (SWs) or magnons. They are promising for low-power and beyond-CMOS information processing, which do not suffer from the ohmic losses. SWs in ferromagnets (antif ...
EPFL2023Micromechanics of oxide inclusions in ferrous alloys
Oxide inclusions are inevitably present in steel as a direct consequence of the steelmaking process; as a result, a cubic centimetre of modern steel will generally contain about a million of these hard and brittle micrometre-sized ceramic particles. Inclus ...
EPFL2023X-ray absorption linear dichroism at the Ti K-edge of rutile (001) TiO2 single crystal
Majed Chergui, Oliviero Cannelli, Giulia Fulvia Mancini, Thomas Charles Henry Rossi, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Jérémy Raymond Jean Maurice Rouxel
X-ray absorption linear dichroism of rutile TiO2 at the Ti K-edge provides information about the electronic states involved in the pre-edge transitions. Here, linear dichroism with high energy resolution is analyzed in combination with ab initio finite dif ...
INT UNION CRYSTALLOGRAPHY2020Control of groundwater pH during bioremediation: Improvement and validation of a geochemical model to assess the buffering potential of ground silicate minerals
David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix
Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. The use of ground silicate minerals mixed with groundwater is an appealing buffering strategy as silicate minerals may act as long-term s ...
Elsevier2014Using Silicate Mineral Particles for pH Control during in situ Bioremediation of Chlorinated Ethene Source Zones
Soil and groundwater pollution by chlorinated solvents such as tricholorethene (TCE) and tetrachloroethene (PCE) is a frequent problem in the industrialized world. Chlorinated solvents, characterized by a low solubility and a density greater than water, fo ...
EPFL2013Utilization of Silicate Minerals for pH Control during In Situ Bioremediation of Chlorinated Solvents
David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix
Background/Objectives. Chloroethenes such as tetrachloroethene (PCE) and trichloroethene (TCE) are among the most prevalent contaminants in groundwater due to their extensive use in industrial processes. In situ bioremediation (ISB) is an attractive techno ...
2012Numerical modeling of field scale application of ground silicate minerals for groundwater pH buffering
David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix
Recently, it was shown that ground silicate minerals are a potentially suitable pH buffering material for contaminated soils undergoing acidification, for example due to acid mine leachate and coal pile runoff infiltration, as well as during the degradatio ...
