Discovery of Giant Unit-Cell Super-Structure in the Infinite-Layer Nickelate PrNiO
J. Oppliger, J. Küspert, A. -C. Dippel +10
Spectacular quantum phenomena such as superconductivity often emerge in flat-band systems where Coulomb interactions overpower electron kinetics. Engineering strategies for flat-ba…
Time-resolved diffraction and photoelectron spectroscopy investigation of the reactive molecular beam epitaxy of ultrathin films
Tobias Pohlmann, Martin Hoppe, Jannis Thien +10
We present time-resolved high energy x-ray diffraction (tr-HEXRD), time-resolved hard x-ray photoelectron spectroscopy (tr-HAXPES) and time-resolved grazing incidence small angle x…
Spatially Inhomogeneous Competition between Superconductivity and the Charge Density Wave in YBaCuO
J. Choi, O. Ivashko, E. Blackburn +13
The charge density wave in the high-temperature superconductor YBaCuO (YBCO) is now known to have two different ordering tendencies differentiated by their -axis…
High-temperature ferroelectric order and magnetic field-cooled effect driven magnetoelectric coupling in R2BaCuO5 (R= Er, Dy, Sm)
A. Indra, S. Mukherjee, S. Majumdar +3
The high-temperature ferroelectric order and a remarkable magnetoelectric effect driven by the magnetic field cooling are reported in R2BaCuO5 (R = Er, Dy, Sm) series. The ferroele…
Ferroelectric order associated with an ordered occupancy at the octahedral site of the inverse spinel structure of multiferroic NiFe2O4
J. K. Dey, A. Chatterjee, S. Majumdar +4
We report a ferroelectric order at ~ 98 K for NiFe2O4, which carries an inverse spinel structure with a centrosymmetric Fd3m structure at room temperature. The value of spontaneous…
Pressure-Induced Rotational Symmetry Breaking in URuSi
J. Choi, O. Ivashko, N. Dennler +8
Phase transitions and symmetry are intimately linked. Melting of ice, for example, restores translation invariance. The mysterious hidden order (HO) phase of URuSi has, des…
Atomic level structure of Ge-Sb-S glasses: chemical short range order and long Sb-S bonds
Ildikó Pethes, Virginie Nazabal, Julien Ari +7
The structure of GeSbS, GeSbS and GeSbS glasses was investigated by neutron diffraction (ND), X-ray diffraction (XRD)…
Competing charge, spin, and superconducting orders in underdoped YBa2Cu3Oy
M. Huecker, N. B. Christensen, A. T. Holmes +9
To explore the doping dependence of the recently discovered charge density wave (CDW) order in YBa2Cu3Oy, we present a bulk-sensitive high-energy x-ray study for several oxygen con…
X-ray diffraction observation of charge density wave order at zero magnetic field in ortho-II YBaCuO
E. Blackburn, J. Chang, M. Hucker +10
X-ray diffraction measurements show that the high-temperature superconductor YBaCuO, with ortho-II oxygen order, has charge density wave order (CDW) in the absence…
