Distinct pressure evolution of coupled nematic and magnetic order in FeSe
Anna E. Böhmer, Karunakar Kothapalli, Wageesha T. Jayasekara +13
FeSe, despite being the structurally simplest compound in the family of iron-based superconductors, shows an astoundingly rich interplay of physical phenomena including nematicity…
Hedgehog spin-vortex crystal stabilized in a hole-doped iron-based superconductor
W. R. Meier, Q. -P. Ding, A. Kreyssig +12
Magnetism is widely considered to be a key ingredient of unconventional superconductivity. In contrast to cuprate high-temperature superconductors, antiferromagnetism in Fe-based s…
Collapsed Tetragonal Phase Transition in LaRuP
Gil Drachuck, Aashish Sapkota, Wageesha Jayasekara +5
The structural properties of LaRuP under external pressure have been studied up to 14 GPa, employing high-energy x-ray diffraction in a diamond-anvil pressure cell. At ambi…
Pressure induced half-collapsed-tetragonal phase in CaKFeAs
Udhara S. Kaluarachchi, Valentin Taufour, Aashish Sapkota +11
We report the temperature-pressure phase diagram of CaKFeAs established using high pressure electrical resistivity, magnetization and high energy x-ray diffraction measurem…
Strong cooperative coupling of pressure-induced magnetic order and nematicity in FeSe
K. Kothapalli, A. E. Böhmer, W. T. Jayasekara +10
A hallmark of the iron-based superconductors is the strong coupling between magnetic, structural and electronic degrees of freedom. However, a universal picture of the normal state…
Origin of the Resistivity Anisotropy in the Nematic Phase of FeSe
M. A. Tanatar, A. E. Böhmer, E. I. Timmons +7
The in-plane resistivity anisotropy is studied in strain-detwinned single crystals of FeSe. In contrast to other iron-based superconductors, FeSe does not develop long-range magnet…
