Combined experimental and theoretical studies of pressure effects in La2Sb
(2017-01-01)
The 5 K superconductor La2Sb shares some structural similarities with the iron-pnictides and -chalgogenides, especially the so-called 122-compounds, despite lacking a 3d-metal component. In order to look for similarities ...
Multifractal scaling of flux penetration in the Iron-based Superconductor Ba(Fe0.925Co0.075)2As2
(American Physical Society, 2013-03-26)
The penetration of magnetic flux fronts in the optimally doped iron based superconductor<br />Ba(Fe0:925Co0:075)2As2 is studied by means of magneto-optic imaging and Bitter decoration. The higher-order analysis of roughening ...
The Role Of Magnetic Excitations In Magnetoresistance And Hall Effect Of Slightly Tm-substituted Bafe2as2 Compounds (tm = Mn, Cu, Ni)
(Elsevier Science BVAmsterdam, 2016)
Disorder, critical currents, and vortex pinning energies in isovalently substituted BaFe2(As1_xPx)2
(American Physical Society, 2013-03)
We present a comprehensive overview of vortex pinning in single crystals of the isovalently substituted iron-based superconductor BaFe2(As1−xPx)2, a material that qualifies as an archetypical clean superconductor, containing ...
The role of magnetic excitations in magnetoresistance and Hall effect of slightly TM-substituted BaFe2As2 compounds (TM = Mn, Cu, Ni)
(Elsevier Science, 2016-12-15)
We report on electrical resistivity, magnetoresistance (MR) and Hall effect measurements in four non-superconducting BaFe2−xTMxAs2 (TM = Mn, Cu and Ni) single crystals with small values of the chemical substitution x. The ...
Possible Unconventional Superconductivity In Substituted Bafe 2 As 2 Revealed By Magnetic Pair-breaking Studies
(Nature Publishing Group, 2014)
Arsenic-bridged magnetic interactions in an emerging two-dimensional FeAs nanostructure on MnAs
(American Physical Society, 2015-08)
The extreme case of an Fe monolayer deposited onto a manganese arsenide (MnAs) substrate is analyzed using density functional theory. We find that an FeAs quasi-two-dimensional antiferromagnetic surface nanostructure ...
Site Specific Spin Dynamics In Bafe2as2: Tuning The Ground State By Orbital Differentiation
(Nature Publishing Group, 2014)
A revision of the fishtail effect in YBa2Cu3O7-δ crystals and its connection with vortex dynamics
(Elsevier Science, 2014-11)
The fishtail magnetization observed in many type II superconductors has been investigated since the earliest nineties and associated with different phase transitions and dynamic crossovers in complex vortex matter. In ...
