Interplay of structure and magnetism in LuFe4Ge2 tuned by hydrostatic pressure
M. O. Ajeesh, P. Materne, R. D. dos Reis +15
LuFeGe crystallizes in the ZrFeSi-type structure, hosting chains of Fe-tetrahedra giving rise to geometric frustration and low-dimensionality. The compound orders a…
Bandwidth controlled insulator-metal transition in BaFeS: A Mössbauer study under pressure
Philipp Materne, Wenli Bi, Jiyong Zhao +6
BaFeS is a quasi one-dimensional Mott insulator that orders antiferromagnetically below 117(5)\,K. The application of pressure induces a transition to a metallic state, and…
Microscopic phase diagram of LaFeAsO single crystals under pressure
Philipp Materne, Wenli Bi, Jiyong Zhao +6
We investigated LaFeAsO single crystals by means of synchrotron Mössbauer spectroscopy under pressures up to 7.5 GPa and down to 13 K and provide a microscopic phase diagram. We fo…
Superconducting and magnetic phase diagram of RbEuFe4As4 and CsEuFe4As4 at high pressure
Daniel E. Jackson, Derrick VanGennep, Wenli Bi +7
The recently discovered (Rb,Cs)EuFe4As4 compounds exhibit an unusual combination of superconductivity (Tc = 35 K) and ferromagnetism (Tm = 15 K). We have performed a series of x-ra…
Suppression of the magnetic order in CeFeAsO: non-equivalence of hydrostatic and chemical pressure
Philipp Materne, Wenli Bi, Esen Ercan Alp +12
We present a detailed investigation of the electronic properties of CeFeAsO under chemical (As by P substitution) and hydrostatic pressure by means of in-house and synchrotron Möss…
Close proximity of FeSe to a magnetic quantum critical point as revealed by high-resolution SR measurements
V. Grinenko, R. Sarkar, P. Materne +12
A nematic transition preceding a long-range spin density wave antiferromagnetic phase is a common feature of many Fe based superconductors. However, in the FeSe system with a nemat…
Magnetic order and spin dynamics across a ferromagnetic quantum critical point: SR investigations of YbNi(PAs)
R. Sarkar, J. Spehling, P. Materne +5
In the quasi-1D heavy-fermion system YbNi(PAs) the presence of a ferromagnetic (FM) quantum critical point (QCP) at with unconventional quan…
Fast recovery of the stripe magnetic order by Mn/Fe substitution in F-doped LaFeAsO superconductors
M. Moroni, P. Carretta, G. Allodi +8
As Nuclear Magnetic (NMR) and Quadrupolar (NQR) Resonance were used, together with Mössbauer spectroscopy, to investigate the magnetic state induced by Mn for Fe substitutio…
Solitonic spin-liquid state due to the violation of the Lifshitz condition in FeTe
Ph. Materne, C. Koz, U. K. Rößler +6
A combination of phenomenological analysis and Mössbauer spectroscopy experiments on the tetragonal FeTe system indicates that the magnetic ordering transition in compounds…
Interplay of magnetism and superconductivity in EuFe(AsP) single crystals probed by muon spin rotation and Fe Mössbauer spectroscopy
Til Goltz, Sirko Kamusella, Hirale S. Jeevan +6
We present our results of a local probe study on EuFe(AsP) single crystals with =0.13, 0.19 and 0.28 by means of muon spin rotation and Fe Mös…

Til Goltz, Veronika Zinth, Dirk Johrendt +5
We present a detailed investigation of the electronic phase diagram of effectively charge compensated Ba1-xKx(Fe1-yCoy)2As2 with x/2 = y. Our experimental study by means of x-ray d…
Microscopic co-existence of superconductivity and magnetism in Ba1-xKxFe2As2
Erwin Wiesenmayer, Hubertus Luetkens, Gwendolyne Pascua +6
It is widely believed that, in contrast to its electron doped counterparts, the hole doped compound Ba1-xKxFe2As2 exhibits a mesoscopic phase separation of magnetism and supercondu…
