Evolution from localized to intermediate valence regime in Ce2Cu2-xNixIn
A. P. Pikul, D. Kaczorowski
Polycrystalline samples of the solid solution Ce2Cu2-xNixIn were studied by means of x-ray powder diffraction, magnetic susceptibility and electrical resistivity measurements perfo…
The Pressure Effects on Electronic Structure of Iron Chalcogenide Superconductors FeSeTe
A. Ciechan, M. J. Winiarski, M. Samsel-Czekała
We study the electronic structure of iron-based superconductors FeSeTe within the density functional theory. We pay particular attention to the pressure effects on the…
Interplay between spin density wave and superconductivity in '122' iron pnictides: 57Fe Mössbauer study

Iron-based superconductors Ba0.7Rb0.3Fe2As2 and CaFe1.92Co0.08As2 of the '122' family have been investigated by means of the 14.41-keV Moessbauer transition in 57Fe versus temperat…
Interplay between magnetism and superconductivity in EuFe(2-x)Co(x)As2 studied by 57Fe and 151Eu Mössbauer spectroscopy
A. Blachowski, K. Ruebenbauer, J. Zukrowski +4
The compound EuFe(2-x)Co(x)As2 was investigated by means of the 57Fe and 151Eu Moessbauer spectroscopy versus temperature (4.2 - 300 K) for x=0 (parent), x=0.34 - 0.39 (superconduc…
Study of the anisotropic magnetic order of the Eu sublattice in single crystals of EuFe_2-xCo_xAs_2 (x = 0, 0.2) by means of magnetization and magnetic torque
Z. Guguchia, S. Bosma, S. Weyeneth +5
Here, we present a combination of magnetization and magnetic torque experiments to investigate the magnetic orders in undoped EuFe2As2 and Co doped EuFe1.8Co0.2As2 single crystals.…
Quantum creep in layered antiferromagnetic superconductor
Tomasz Krzyszton
In the mixed state of layered superconductor the antiferromagnetic order of magnetic ions can create the spin-flop domains along the phase cores of the Josephson vortices. The pape…
Muon-spin rotation measurements of the magnetic penetration depth in the Fe-based superconductor Ba_(1-x)Rb_(x)Fe2As2
Z. Guguchia, Z. Shermadini, A. Amato +7
Measurements of the magnetic penetration depth (lambda) in the Fe-based superconductor Ba_(1-x)Rb_xFe_2As_2 (x=0.3, 0.35, 0.4) were carried out using the muon-spin rotation muSR te…
Capability of the free-ion eigenstates for crystal-field splitting
Jacek Mulak, Maciej Mulak
Any electron eigenstate |Ψ>of the paramagnetic ion open-shell is characterized by the three independent multipole asphericities A_{k}=<Ψ|| C^(k)}||Ψ> for k=2,4 and 6 related to the…
Isothermal magnetocaloric effect in the vicinity of the Lifshitz point in Mn_{0.9}Co_{0.1}P
Tomasz Plackowski, Marcin Matusiak, Jozef Sznajd
The magnetic field - temperature (B - T) phase diagram of the Mn0.9Co0.1P single crystal is studied in the vicinity of the Lifshitz point by means of isothermal magnetocaloric coef…
Doping driven Small-to-Large Fermi surface transition and d-wave superconductivity in a two-dimenional Kondo lattice
R. Eder, P. Wrobel
We study the two-dimensional Kondo lattice model with an additional Heisenberg exchange between localized spins. In a first step we use mean-field theory with two order parameters.…

We report a systematic study of the transport properties in the series of Eu(Fe1-xCox)2As2 single crystals with x = 0, 0.15, 0.20 and 0.30. Spin-density-wave order is observed in t…
A fundamental requirement for crystal-field parametrization
Jacek Mulak, Maciej Mulak
The physically correct parametrization of the energy levels of transition ions in crystals in terms of crystal-field (CF) Hamiltonians ${\cal H}_{\rm CF}=\sum_{k}\sum_{q}B_{kq}C_{q…
