The Role of Structural Imperfections in Sr2FeMoO6 Thin Films
(Turun yliopistoAnnales Universitatis Turkuensis A I 527, 2015-11-28)
In this work, Sr2FeMoO6 (SFMO) thin films were studied with the main focus on their magnetic and magneto-transport properties. The fabrication process of pulsed laser deposited SFMO films was first optimized. Then the ...
Beyond the Cosmological Principle
(Turun yliopistoAnnales Universitatis Turkuensis A I 545, 2016-09-14)
Simplifying the Einstein field equation by assuming the cosmological principle yields a set of differential equations which governs the dynamics of the universe as described in the cosmological standard model. The cosmological ...
Time-dependent Quantum Systems
(Turun yliopistoAnnales Universitatis Turkuensis A I 561, 2017-06-02)
This thesis discusses different aspects of time-dependent two-level quantum systems and their coherent dynamics. In the introductory chapters, we present some basic models used to study them and some basic results ...
The Role of Dopant Morphology in Superconducting YBa2Cu3O7-delta Thin Films
(Turun yliopisto, 2017-12-02)
In this work, the effect of BaCeO3 (BCO) and BaZrO3 (BZO) dopants on structural and superconducting properties of YBa2Cu3O7−d (YBCO) superconducting thin films was studied. The main focus was in the flux pinning properties ...
