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…
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-…
