Effect of Co doping and hydrostatic pressure on SrFe2As2
E. Lengyel, M. Kumar, W. Schnelle +2
We report a pressure study on electron doped SrFeCoAs by electrical-resistivity () and magnetic-susceptibility () experiments. Application of either external…
Superconducting properties of KNaFeAs under pressure
V. Grinenko, W. Schottenhamel, A. U. B. Wolter +18
The effect of hydrostatic pressure and partial Na substitution on the normal-state properties and the superconducting transition temperature () of KNaFeAs…
Evidence of d-wave Superconductivity in K_(1-x)Na_xFe_2As_2 (x = 0, 0.1) Single Crystals from Low-Temperature Specific Heat Measurements
M. Abdel-Hafiez, V. Grinenko, S. Aswartham +20
From the measurement and analysis of the specific heat of high-quality K_(1-x)Na_xFe_2As_2 single crystals we establish the presence of large T^2 contributions with coefficients al…
KFe2As2: coexistence of superconductivity and local moment derived spin-glass
V. Grinenko, M. Abdel-Hafiez, S. Aswartham +9
High-quality KFe2As2 single crystals have been studied by transport, magnetization and low-T specific heat measurements. Their analysis shows that superconductivity occurs (in some…
Hole-doping in BaFeAs: The case of BaNaFeAs single crystals
S. Aswartham, M. Abdel-Hafiez, D. Bombor +11
Single crystals of BaNaFeAs with = 0, 0.25, 0.35, 0.4 were grown using a self-flux high temperature solution growth technique. The superconducting and norma…
Competition of local-moment ferromagnetism and superconductivity in Co-substituted EuFe2As2
M. Nicklas, M. Kumar, E. Lengyel +2
In contrast to SrFe2As2, where only the iron possesses a magnetic moment, in EuFe2As2 an additional large, local magnetic moment is carried by Eu2+. Like SrFe2As2, EuFe2As2 exhibit…
