Coupled Magnetic and Superconducting Transitions in SrVOFeAs Under Pressure
S. Holenstein, F. Hummel, Z. Guguchia +11
We report muon spin rotation (SR) and magnetization measurements on superconducting SrVOFeAs under pressure. At ambient pressure, SrVOFeAs undergoes an a…
Magnetic Field tuning of low energy spin dynamics in the single-atomic magnet Li(LiFe)N
S. A. Braeuninger, A. Jesche, S. Kamusella +5
We present a systematic 57Fe-Moessbauer study on highly diluted Fe centers in Li2(Li1-xFex)N single-crystals as a function of temperature and magnetic field applied transverse and…
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…
Spin-order-induced multiferroicity in LiCuFe2(VO4)3 and disorder effects in NaCuFe2(VO4)3
A. V. Koshelev, K. V. Zakharov, L. V. Shvanskaya +10
Mixed spin chain compounds, ACuFe2(VO4)3 (A= Li,Na), reach magnetically ordered state at TN ~ 11 K (Li) or ~ 9 K (Na) and experience further transformation of magnetic order at T*…
Nematic Fluctuations in Iron-Oxychalcogenide Mott Insulators
B. Freelon, R. Sarkar, S. Kamusella +19
Nematic fluctuations occur in a wide range of physical systems from liquid crystals to biological molecules to solids such as exotic magnets, cuprates and iron-based high- sup…
Magnetic order and spin dynamics in the helical magnetic system FePOO
R. Sarkar, S. Kamusella, S. A. Braeuninger +8
The 3-electronic spin dynamics and the magnetic order in FePOO were investigated by muon spin rotation and relaxation (SR) and Fe Mössbauer spectroscopy. Z…
Diluted paramagnetic impurities in nonmagnetic BaYIrO
F. Hammerath, R. Sarkar, S. Kamusella +9
The cubic double perovskite BaYIrO has been investigated by the local probe techniques nuclear magnetic resonance (Y NMR) and muon spin rotation (muSR). Both methods…
Non-collinear antiferromagnetism of coupled spins and pseudospins in the double perovskite La2CuIrO6
Kaustuv Manna, R. Sarkar, S. Fuchs +19
We report the structural, magnetic and thermodynamic properties of the double perovskite compound La2CuIrO6 from X-ray, neutron diffraction, neutron depolarization, dc magnetizatio…
Coexistence of low moment magnetism and superconductivity in tetragonal FeS and suppression of under pressure
S. Holenstein, U. Pachmayr, Z. Guguchia +8
We report local probe (SR) measurements on the recently discovered tetragonal FeS superconductor which has been predicted to be electronically very similar to superconducting Fe…
Superconducting properties and pseudogap from preformed Cooper pairs in the triclinic (CaFePtAs)PtAs
M. A. Surmach, F. Brückner, S. Kamusella +11
Using a combination of muon-spin relaxation (SR), inelastic neutron scattering (INS) and nuclear magnetic resonance (NMR), we investigated the novel iron-based superconductor wi…
