Orthogonal spin arrangement as possible ground state of three - dimensional Shastry - Sutherland network in Ba3Cu3In4O12
O. S. Volkova, I. S. Maslova, R. Klingeler +4
The Ba3Cu3In4O12 stands for unique topology of the magnetic subsystem. It consists of rotated by 90\Box relative to each other "paper-chain" columns made of vertex-sharing CuIO…
Magnetic properties and revisited exchange integrals of the frustrated chain cuprate PbCuSO(OH) - linarite
A. U. B. Wolter, F. Lipps, M. Schäpers +12
We present a detailed study in the paramagnetic regime of the frustrated = 1/2 spin-compound linarite, PbCuSO(OH), with competing ferromagnetic nearest-neighbor and ant…
Specific heat and upper critical field in KFe2As2 single crystals
M. Abdel-Hafiez, S. Aswartham, S. Wurmehl +6
We report low-temperature specific heat measurements for high-quality single crystalline KFe2As2 (T_c about 3.5 K). The investigated zero-field specific heat data yields an unusual…
Calorimetric study of the superconducting and normal state properties of Ca(Fe1-xCox)2As2
M. Abdel-Hafiez, L. Harnagea, S. Singh +5
We present a calorimetric study on single crystals of Ca(Fe1-xCox)2As2 (x = 0, 0.032, 0.051, 0.056, 0.063, and 0.146). The combined first order spin-density wave/structural transit…
Multi-gap superconductivity in single crystals of BaNaFeAs: A calorimetric investigation
A. K. Pramanik, M. Abdel-Hafiez, S. Aswartham +4
We investigate the electronic properties and the superconducting gap characteristics of a single crystal of hole-doped 122 Fe-pnictide BaNaFeAs by means o…
