Electron doping of the iron-arsenide superconductor CeFeAsO controlled by hydrostatic pressure
K. Mydeen, A. Jesche, K. Meier-Kirchner +4
In the iron-pnictide material CeFeAsO not only the Fe moments, but also the local 4f moments of the Ce order antiferromagnetically at low temperatures. We elucidate on the peculiar…
Molecular beam epitaxy preparation and in situ characterization of FeTe thin films
V. M. Pereira, C. N. Wu, C. E. Liu +8
We have synthesized FeTe thin films by means of molecular beam epitaxy (MBE) under Te-limited growth conditions. We found that epitaxial layer-by-layer growth is possible f…
Pressure-induced ferromagnetism due to an anisotropic electronic topological transition in Fe1.08Te
K. Mydeen, D. Kasinathan, C. Koz +8
A rapid and anisotropic modification of the Fermi-surface shape can be associated with abrupt changes in crystalline lattice geometry or in the magnetic state of a material. In thi…
Suppression of the ferromagnetic order in the Heusler alloy Ni50Mn35In15 by hydrostatic pressure
C. Salazar Mejia, K. Mydeen, P. Naumov +7
We report the effect of hydrostatic pressure on the magnetic and structural properties of the shape-memory Heusler alloy Ni50Mn35In15. Magnetization and x-ray diffraction experimen…
Solitonic spin-liquid state due to the violation of the Lifshitz condition in FeTe
Ph. Materne, C. Koz, U. K. Rößler +6
A combination of phenomenological analysis and Mössbauer spectroscopy experiments on the tetragonal FeTe system indicates that the magnetic ordering transition in compounds…
Pressure-induced phase transitions and high-pressure tetragonal phase of Fe1.08Te
C. Koz, S. Rößler, A. A. Tsirlin +6
We report the effects of hydrostatic pressure on the temperature-induced phase transitions in Fe1.08Te in the pressure range 0-3 GPa using synchrotron powder x-ray diffraction (XRD…
