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…
Possible unconventional superconductivity in substituted BaFeAs revealed by magnetic pair-breaking studies
P. F. S. Rosa, C. Adriano, T. M. Garitezi +8
The possible existence of a sign-changing gap symmetry in BaFeAs-derived superconductors (SC) has been an exciting topic of research in the last few years. To further i…
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…
Hydrostatic and chemical pressure tuning of CeFeAs_1-xP_xO single crystals
K. Mydeen, E. Lengyel, A. Jesche +2
We carried out a combined P-substitution and hydrostatic pressure study on CeFeAs_1-xP_xO single crystals in order to investigate the peculiar relationship of the local moment magn…
Temperature - pressure phase diagram of the superconducting iron pnictide LiFeP
K. Mydeen, E. Lengyel, Z. Deng +3
Electrical-resistivity and magnetic-susceptibility measurements under hydrostatic pressure up to p = 2.75 GPa have been performed on superconducting LiFeP. A broad superconducting…
