Journal ArticleDOI
Orbital Reconstruction and Covalent Bonding at an Oxide Interface
Jak Chakhalian,Jak Chakhalian,John W. Freeland,H.-U. Habermeier,Georg Cristiani,Giniyat Khaliullin,M. van Veenendaal,M. van Veenendaal,Bernhard Keimer +8 more
TL;DR: This work has investigated the interface between high-temperature superconducting (Y,Ca)Ba2Cu3O7 and metallic La0.67Ca0.33MnO3 by resonant x-ray spectroscopy and indicates the formation of a strong chemical bond between Cu and Mn atoms across the interface.
Journal ArticleDOI
Magnetism at the interface between ferromagnetic and superconducting oxides
Jak Chakhalian,Jak Chakhalian,John W. Freeland,George Srajer,J. Strempfer,Giniyat Khaliullin,Julio C. Cezar,Timothy Charlton,Robert M. Dalgliesh,Christian Bernhard,Georg Cristiani,H.-U. Habermeier,Bernhard Keimer +12 more
TL;DR: In this paper, the authors examined superlattices composed of the half-metallic ferromagnet La2/3Ca1/3MnO3 and the high-temperature superconductor YBa2Cu3O7 by absorption spectroscopy with circularly polarized X-rays and by off-specular neutron reflectometry.
Journal ArticleDOI
Quantitative Comparison of Mixed Conducting SOFC Cathode Materials by Means of Thin Film Model Electrodes
F. S. Baumann,Jürgen Fleig,Georg Cristiani,Benjamin Stuhlhofer,H.-U. Habermeier,Joachim Maier +5 more
TL;DR: In this paper, it was found that substitution of the A-site cation La in La 1-x Sr x Co 1-y Fe y O 3-δ by Sm and especially by Ba leads to a strong enhancement of the surface exchange kinetics, whereas a variation of the Co/Fe ratio between 0 and 1 has only little effect on this quantity at temperatures around 750°C.
Journal ArticleDOI
Magnetic proximity effect in perovskite superconductor/ferromagnet multilayers
J. Stahn,Jak Chakhalian,Ch. Niedermayer,J. Hoppler,T. Gutberlet,J. Voigt,F. Treubel,H.-U. Habermeier,Georg Cristiani,Bernhard Keimer,Christian Bernhard +10 more
TL;DR: In this paper, the authors identify two possible magnetization profiles: (i) a magnetic moment within the superconducting/ferromagnetic (SC/FM) layer antiparallel to the one in the FM layer (antiphase magnetic proximity effect) or (ii) a ''dead'' region with zero net magnetic moment.
Journal ArticleDOI
Giant superconductivity-induced modulation of the ferromagnetic magnetization in a cuprate–manganite superlattice
J. Hoppler,Jochen Stahn,Ch. Niedermayer,Vivek Kumar Malik,Houssny Bouyanfif,Alan J. Drew,Matthias Rössle,Alexandre I. Buzdin,Georg Cristiani,H.-U. Habermeier,Bernhard Keimer,Christian Bernhard +11 more
TL;DR: In this paper, the authors present neutron reflectometry measurements of a [Y(0.6)Pr( 0.4)Ba(2)Cu(3)O(7) (10 nm) superlattice, which reveal a surprisingly large superconductivityinduced modulation of the vertical ferromagnetic magnetization profile.
