Persistent Magnetism in Silver-doped BaFe2As2 Crystals
Li Li, Huibo Cao, David S. Parker +2
We investigate the thermodynamic and transport properties of silver-substituted BaFe2As2 (122) crystals, up to ~4.5%. Similar to other transition-metal substitutions in 122, Ag dim…
The magnetic precursor of the pressure-induced superconductivity in Fe-ladder compound
Songxue Chi, Yoshiya Uwatoko, Huibo Cao +4
The pressure effects on the antiferromagentic orders in iron-based ladder compounds CsFeSe and BaFeS have been studied using neutron diffraction. With identical cry…
Anomalous magneto-elastic and charge doping effects in thallium-doped BaFe2As2
A. S. Sefat, L. Li, H. B. Cao +4
Within the BaFe2As2 crystal lattice, we partially substitute thallium for barium and report the effects of interlayer coupling in Ba1-xTlxFe2As2 crystals. We demonstrate the unusua…
Mott localization in a pure stripe antiferromagnet RbFeS
Meng Wang, Ming Yi, Huibo Cao +8
A combination of neutron diffraction and angle-resolved photoemission spectroscopy measurements on a pure antiferromagnetic stripe RbFeS is reported. A neutro…
Role of Magnetism in Superconductivity of BaFe2As2: Study of 5d Au-doped Crystals
Li Li, Huibo B. Cao, Michael A. McGuire +3
We investigate properties of BaFe2As2 (122) single crystals upon gold doping, which is the transition metal with the highest atomic weight. The Au substitution into the FeAs-planes…
Structural and magnetic phase transitions in CaLaFeAs with electron overdoped FeAs layers
Shan Jiang, Chang Liu, Huibo Cao +15
We report a study of the CaLaFeAs single crystals. We unravel a monoclinic to triclinic phase transition at 58 K, and a paramagnetic to stripe antiferromagnet…
A Mott insulator continuously connected to iron pnictide superconductors
Yu Song, Zahra Yamani, Chongde Cao +18
Iron-based superconductivity develops near an antiferromagnetic order and out of a bad metal normal state, which has been interpreted as originating from a proximate Mott transitio…
Strong Interplay between Stripe Spin Fluctuations, Nematicity and Superconductivity in FeSe
Qisi Wang, Yao Shen, Bingying Pan +13
Elucidating the microscopic origin of nematic order in iron-based superconducting materials is important because the interactions that drive nematic order may also mediate the Coop…
Structural and Magnetic Phase Diagram of CrAs and its Relationship with Pressure-induced Superconductivity
Yao Shen, Qisi Wang, Yiqing Hao +11
Most unconventional superconductors, including cuprates and iron-based superconductors, are derived from chemical doping or application of pressure on their collinearly magnetic-or…
Absence of structural transition in TM0.5IrTe2 (TM=Mn, Fe, Co, Ni)
J. -Q. Yan, B. Saparov, A. S. Sefat +5
TM-doped IrTe2(TM=Mn, Fe, Co, Ni) compounds were synthesized by solid state reaction. Single crystal x-ray diffraction experiments indicate that part of the doped TM ions (TM=Fe, C…
Flux growth and physical properties of Mo3Sb7 single crystals
J. -Q. Yan, M. A. McGuire, A. F. May +4
