Grenzflächen- und Verspannungseffekte in La₁₋ₓSrₓMnO₃-Dünnschichten
(2024-12-19)In this dissertation, strain and interface effects on La₁₋ₓSrₓMnO₃ (LSMO) thin films with doping levels 0 ≤ x ≤ 0.6 are investigated by Raman spectroscopy and surface-enhanced Raman spectroscopy (SERS). For undoped LaMnO₃, ... -
Magneto-thermal conductivity of perovskite manganite films and exchange-spring coupled superlattices
(2024-02-21)In this thesis, thin colossal magnetoresistive perovskite manganite films and superlattices forming an exchange spring magnet were studied regarding their magneto-thermal conductivity. Using the metalorganic aerosol ... -
Non-equilibrium Phases in Jahn-Teller-distorted Perovskite Manganites
(2023-12-04)Optical control of condensed matter, being inherently fast and energy efficient, sparks hope for potential technical applications. However, these require a fundamental understanding of the physical mechanisms behind. In ... -
Kationordnung und Grenzflächeneffekte in stark korrelierten Elektronensystemen
(2021-10-05)The work is about cation ordering and interface mechanism in strongly correlated electron systems -
Polaronic behaviour at manganite interfaces studied by advanced Raman scattering techniques
(2020-03-20)This work focusses on the polaronic behaviour at manganite interfaces studied by various Raman spectroscopy techniques. Temperature- and magnetic-field-dependent studies probe the polaronic behaviour at the internal ... -
Ordnungs-/Unordnungsphänomene in korrelierten Perowskitschichten anhand von fortgeschrittener Raman-Spektroskopie
(2018-10-08)Perovskite oxides exhibit, depending on the composition, structural distortions, electronic correlations and ordering/disordering phenomena, a huge variety of electrical and magnetic properties, which is offering a versatile ... -
Mikrostruktur und elektrischer Transport von Sr<sub>1-x</sub>Ca<sub>x</sub>RuO<sub>3</sub>-Dünnfilmen – Der Weg zur Aufdeckung des Fermiflüssigkeitgrundzustandes in CaRuO<sub>3</sub>
(2018-10-02)The present document deals with the material system Sr_(1-x)Ca_(x)RuO_(3). The deposition of highest quality thin films was the central interest as the requirement for the research of electrical transport. Thin films are ... -
Gestaltung der elektronischen Korrelationen in Perowskit-Heterostrukturen auf atomarer Skala
(2016-01-19)For the deposition of high quality heterostructures consisting of transition metal perovskites a new system for metalorganic aerosol deposition with growth control by in-situ ellipsometry was developed. By numerical ... -
Zusammenspiel von Ladungs-, Gitter- und magnetischen Ordnungen in hochdotierten LCMO Schichten
(2015-07-27)This work is focused on the preparation and characterization of overdoped La_1-xCa_xMnO_3 films on MgO and as freestanding films. The charge ordering transition is being investigated via means of resistance, magnetization, ... -
Kationen-Ordnung in ferri/ferromagnetischen perowskitischen Dünnfilmen
(2015-07-27)A major obstacle to the applicability of oxide perovskites in electrical or spintronic applications is the size of the specific temperatures at which the physical phenomena such as ferromagnetism or high-temperature ...
