Room temperature cathodoluminescence quenching of Er3+ in AlNOEr
Valerie Brien, P. R. Edwards, Pascal Boulet +1
This paper reports a cathodoluminescence (CL) spectroscopic study of nanogranular AlNOErx samples with erbiumcontent, x, in the range 0.5--3.6 at%. A wide range of erbium concentra…
Influence of interlayer exchange coupling on ultrafast laser-induced magnetization reversal in ferromagnetic spin valves
Junta Igarashi, Yann Le Guen, Julius Hohlfeld +4
In this study, we explore the influence of interlayer exchange coupling on magnetization reversal triggered by femtosecond laser pulses in ferromagnetic spin valves. Our experiment…
Controlling effective field contributions to laser-induced magnetization precession by heterostructure design
Jasmin Jarecki, Maximilian Mattern, Fried-Conrad Weber +6
Nanoscale heterostructure design can control laser-induced heat dissipation and strain propagation as well as their efficiency for driving magnetization precession. We use insulati…
Scaling and complexity of stress fluctuations associated with smooth and jerky flow in a FeCoNiTiAl high-entropy alloy
Mikhail Lebyodkin, Jamieson Brechtl, Tatiana Lebedkina +3
Recent observations of jerky flow in high-entropy alloys (HEA) revealed a high role of self-organization of dislocations in their plasticity. The present work reports first results…
In-depth investigations of size and occupancies in cobalt ferrite nanoparticles by joint Rietveld refinements of X-ray and neutron powder diffraction data
K. Henry, J. V. Ahlburg, H. L. Andersen +4
Powder X-ray diffraction (PXRD) and neutron powder diffraction (NPD) have been used to investigate the crystal structure of CoFe2O4 nanoparticles prepared via different hydrotherma…
Quantifying Li-content for compositional tailoring of lithium ferrite ceramics
C. Granados-Miralles, A. Serrano, P. Prieto +6
Owing to their multiple applications, lithium ferrites are relevant materials for several emerging technologies. For instance, LiFeO2 has been spotted as an alternative cathode mat…
Persistence of structural distortion and bulk band Rashba splitting in SnTe above its ferroelectric critical temperature
Frédéric Chassot, Aki Pulkkinen, Geoffroy Kremer +8
The ferroelectric semiconductor -SnTe has been regarded as a topological crystalline insulator and the dispersion of its surface states has been intensively measured with angle-…
Heat-conserving three-temperature model for ultrafast demagnetization of 3d ferromagnets
M. Pankratova, I. P. Miranda, D. Thonig +6
We study the ultrafast magnetization dynamics of bcc Fe and fcc Co using the recently suggested heat-conserving three-temperature model (HC3TM), together with atomistic spin- and l…
Quantum Confinement and Electronic Structure at the Surface of van der Waals Ferroelectric α-InSe
Geoffroy Kremer, Aymen Mahmoudi, Adel M'Foukh +11
Two-dimensional (2D) ferroelectric (FE) materials are promising compounds for next-generation nonvolatile memories, due to their low energy consumption and high endurance. Among th…
Carrier-Density Control of the Quantum-Confined 1-TiSe Charge-Density-Wave
T. Jaouen, A. Pulkkinen, M. Rumo +9
Using angle-resolved photoemission spectroscopy, combined with first principle and coupled self-consistent Poisson-Schrödinger calculations, we demonstrate that potassium (K) atoms…
Features of a nano-twist phase in the nanolayered Ti3AlC2 MAX phase
Julien Guénolé, Vincent Taupin, Maxime Vallet +2
Complex intermetallic materials known as MAX phases exhibit exceptional properties from both metals and ceramics, largely thanks to their nanolayered structure. With high-resolutio…
Thermally activated nature of synchro-Shockley dislocations in Laves phases
Zhuocheng Xie, Dimitri Chauraud, Achraf Atila +3
Synchro-Shockley dislocations, as zonal dislocation, are the major carrier of plasticity in Laves phases at high temperatures. The motion of synchro-Shockley dislocations is compos…
Implementation strategies in phonopy and phono3py
Atsushi Togo, Laurent Chaput, Terumasa Tadano +1
Scientific simulation codes are public property sustained by the community. Modern technology allows anyone to join scientific software projects, from anywhere, remotely via the in…
Impact of Severe Plastic Deformation on Kinetics and Thermodynamics of Hydrogen Storage in Magnesium and Its Alloys
Kaveh Edalati, Etsuo Akiba, Walter J. Botta +10
Magnesium and its alloys are the most investigated materials for solid-state hydrogen storage in the form of metal hydrides, but there are still unresolved problems with the kineti…
First-principles study of hydrogen dynamics in monoclinic TiO
S. Vahid Hosseini, Andrei Postnikov, Mohammad Reza Mohammadizadeh
The existence of intrinsic vacancies in cubic (monoclinic) TiO suggests opportunity for hydrogen absorption, which was addressed in recent experiments. In the present work, based o…
