Lay Summary (German)

Lead
Das Projekt ist im Bereich der experimentellen Festkörperphysik angesiedelt. Insbesondere sollen die supraleitenden und magnetischen Eigenschaften von Materialien mit stark korrlierten Elektronen untersucht werden. Dabei handelt es sich um ein recht breites Spektrum von Materialien, welches von Einkristallen der Kuprat und Eisenarsenid Hochtemperatur-Supraleiter bis zu künstlich gewachsenen Vielfachschichtsystemen reicht.
Lay summary

Das Ziel des Forschungsprojektes ist es die ungewöhnlichen elektronischen und magnetischen Eigenschaften von Oxiden und Arseniden mit stark korrelierten Elektronen besser zu verstehen. Zudem sollen die entsprechenden Eigenschaften von künstlich gewachsenen dünnen Schichten und von daraus resultierenden Multischichsystemen erforscht werden. 

Nach Abschluss des Projektes soll der elektronische Normalzustand und der Paarungsmechanismus der Hochtemperatur-Supraleitung besser verstanden sein. Auch sollten neue Effekte an den Grenzschichten ziwschen komplexen Oxiden entdeckt und erforscht sein. Es ist absehbar, dass sich dadurch weitere offene Fragen ergeben.

Die Ergebenisse werden unser  Grundlagenwissen über stark korrelierte elektronische Materialien erweitern. Die gewonnen Erkenntnise können darüber hinaus auch zur  Entwicklung neuer elektronischer Materialien beitragen. Diese werden für eine effizientere und energiesparende  Sensorik und Datenverarbeitung dringend benötigt.

Im Rahmen diese Projektes werden auch neue spektroskopische Methoden entwickelt im Bereich der Terahertz und Infrarortspektroskopie in hohen magnetischen Feldern.

Abstract

This is a continuation proposal for our ongoing research on the interplay between magnetism and superconductivity (SC) in bulk high-Tc SC´s and on the emergent magnetic and electronic phenomena in thin-film-based multilayers from strongly correlated oxides. The multilayers are grown with our in-house PLD system, the single crystals are obtained through collaborations. The experimental techniques are THz- to UV-spectroscopy, in particular, THz- and IR-magneto-ellipsometry up to 7.5 Tesla; muon spin rotation (µSR); polarised neutron reflectometry (PNR); and resonant X-ray absorption, reflectometry and diffraction. The muon, neutron and resonant X-ray experiments are performed at various large scale facilities.We request funding for three PhD students and one Postdoc. The Postdoc is required since he needs to master the complex instrumentation for the PLD thin film growth and characterization and also the THz- and IR-magneto-ellipsometry. They will be working on the following three main topics:A) Interplay of magnetic and electronic orders with high-Tc superconductivity: Using THz- to UV-magneto-ellipsometry and µSR, we will study the various magnetic and electronic orders in the cuprate and iron arsenide high Tc´s and try to clarify their relationship with SC. Specific topics are the dramatic changes of the Fermi-surface around p*?0.19 and the relationship between a static charge density wave and SC in the cuprates and the complex magnetic phase diagram and the role of nematicity in the iron arsenides and selenides. B) Interface-effects in multilayers from cuprates and perovskite oxides: In the first place, we want to understand the mechanism that drives the so-called orbital reconstruction of the Cu ions at the interface of YBa2Cu3O7 (YBCO) with a perovskite oxide like La2/3Ca1/3MnO3. Furthermore, we want to follow up on our recent observation that a granular SC state with an insulator-like dc-resistivity is induced by an unknown interface effect in multilayers of YBCO with manganites, like (Nd,Pr)1-x(Ca1-ySry)xMnO3 (NCSMO), which are in an insulating, antiferromagnetic and charge/orbital ordered state. Notably, a macroscopically coherent SC response can be restored with a magnetic field which suppresses the charge/orbital order in the manganite (toward an itinerant ferromagnetic state). Finally, we want to use the magnetic-field-effect on the charge/orbital order and the related, large orthorhombic distortions in a NCSMO layer to influence the ferroelectric properties of a Sr1-xBaxTiO3 layer that is grown on top. The goal is to obtain a system for which the electric polarization can be rotated or switched on and off with a magnetic field.C) THz- and IR-ellipsometry in high magnetic field: We are developing a world-wide unique setup for THz- and IR-ellipsometry measurements in grazing incidence geometry and high magnetic fields up to 7.5 Tesla (partially financed by the R´EQUIP 206021_163980). This instrument will be used for high precision measurements of the magneto-dielectric tensor of various materials with strongly electronic correlations, including the ones from parts A) and B).
