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…
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…
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…
First-order structural transition in the magnetically ordered phase of Fe1.13Te
S. Rößler, Dona Cherian, W. Lorenz +8
Specific heat, resistivity, magnetic susceptibility, linear thermal expansion (LTE), and high-resolution synchrotron X-ray powder diffraction investigations of single crystals Fe1+…
