Spin-liquid-like ground states in the double hydroxyperovskites CuSn(OD)6 and MnSn(OD)6 evidenced by μSR spectroscopy
Moumita Naskar, Anton A. Kulbakov, Kaushick K. Parui +9
Double hydroxide perovskites with magnetic transition-metal ions were recently identified as a unique class of materials that combine magnetic frustration with correlated proton di…
Magnetic anisotropy and dipolar interactions in the frustrated triangular-lattice magnet NaGdS_2
J. Grumbach, E. HäuÃler, S. Luther +12
In this comprehensive study, we present results of bulk measurements (magnetization, specific heat, ac susceptibility, thermal expansion, and magnetostriction) combined with local…
Ultrasound evidence for multicomponent superconducting order parameter in BaKFeAs with electron quadrupling phase
Chris Halcrow, Ilya Shipulin, Federico Caglieris +6
Experiments have pointed to the formation of the electron quadrupling condensate in BaKFeAs at . The state spontaneously breaks time-reversal symmet…
Magnetic order and Li-diffusion in the 1/3-filled Kagome layers of antiperovskite Lithium-ion battery materials (LiFe)SO and (LiFe)SeO
F. Seewald, T. Schulze, N. GräÃler +8
The recently discovered lithium-rich antiperovskites (LiFe)SeO and (LiFe)SO host lithium and iron ions on the same atomic position which octahedrally coordinates to central…
Contrasting -axis and in-plane uniaxial stress effects on superconductivity and stripe order in LaBaCuO
S. S. Islam, V. Sazgari, J. N. Graham +16
The cuprate superconductor LaBaCuO (LBCO) near is a striking example of intertwined electronic orders, where 3D superconductivity is anomalously suppresse…
Evidence of pseudogap and absence of spin magnetism in the time-reversal-symmetry-breaking state of BaKFeAs
Florian Bärtl, Nadia Stegani, Federico Caglieris +13
Muon-spin-rotation (SR) experiments and the observation of a spontaneous Nernst effect indicate time-reversal symmetry breaking (BTRS) at above the superco…
