Highly mobile carriers in orthorhombic phases of iron-based superconductors FeSeS
Y. A. Ovchenkov, D. A. Chareev, V. A. Kulbachinskii +4
The field and temperature dependencies of the longitudinal and Hall resistivity have been measured for FeSeS (x=0.04, 0.09 and 0.19) single crystals. The sample F…
Unveiling the hidden nematicity and spin subsystem in FeSe
C. W. Luo, P. C. Cheng, S. -H. Wang +7
The nematic order (nematicity) is considered one of the essential ingredients to understand the mechanism of Fe-based superconductivity. In most Fe-based superconductors (pnictides…
Study of the itinerant electron magnetism of Fe-based superconductors by the proximity effect
Yu. N. Chiang, M. O. Dzuba, O. G. Shevchenko +1
We used the proximity effect as a tool to achieve an ideal (barrier - free) NS boundary for quantitative evaluation of transport phenomena that accompany converting dissipative cur…

Igor Presniakov, Igor Morozov, Alexey Sobolev +7
Detailed 57Fe Mossbauer spectroscopy measurements on superconducting NaFeAs powder samples have been performed in the temperature range 13 K < T < 300 K. The 57Fe spectra recorded…
A 57Fe Mössbauer Study Of Local Structure And Spin Arrangements In Antiferromagnetic NaFeAs
Igor Presniakov, Igor Morozov, Alexey Sobolev +5
Detailed 57Fe Mössbauer spectroscopy measurements on superconducting NaFeAs powder crystals have been performed. The 57Fe spectra recorded in the paramagnetic temperature range (T…
Conductance of non-ballistic point contacts in hybrid systems "normal metal/superconductor" Cu/Mo-C and Cu/LaOFFeAs
Yu. N. Chiang, M. O. Dzyuba, O. G. Shevchenko +1
We consider the shape of the curves of "Andreev" conductance of non-ballistic point contact NS heterosystems depending on the bias voltage at the contact. The obtained shape of tho…
Quasiparticle dynamics and phonon softening in FeSe superconductors
C. W. Luo, I. H. Wu, P. C. Cheng +8
Quasiparticle dynamics of FeSe single crystals revealed by dual-color transient reflectivity measurements (ΔR/R) provides unprecedented information on Fe-based superconductors. The…
Coexistence of isotropic s-wave and extended s-wave order parameters in FeSe as revealed by the low-temperature specific heat
J. -Y. Lin, Y. S. Hsieh, D. A. Chareev +3
The comprehensive low-temperature specific heat C(T) data identify both an isotropic s-wave and an extended s-wave order parameters coexisting in a superconducting single crystal F…
Weak superconducting pairing and a single isotropic energy gap in stoichiometric LiFeAs
D. S. Inosov, J. S. White, D. V. Evtushinsky +15
We report superconducting (SC) properties of stoichiometric LiFeAs (Tc = 17 K) studied by small-angle neutron scattering (SANS) and angle-resolved photoemission (ARPES). Although t…
Superconductivity without magnetism in LiFeAs
S. V. Borisenko, V. B. Zabolotnyy, D. V. Evtushinsky +8
The particular shape of the Fermi surface can give rise to a number of collective quantum phenomena in solids, such as density wave orderings or even superconductivity. In many new…
