Designing magnetic heterostructures utilizing a cutting-edge growth technique (molecular beam epitaxy) stabilizes and manifests new quantization phenomena, as confirmed by low-temperature electrical transport and time-domain terahertz magneto-optical measurements. Starting with a review of the theoretical background and recent experimental advances in topological insulators in terms of a novel magneto-electric coupling, the author subsequently explores their magnetic quantum properties and reveals topological phase transitions between quantum anomalous Hall insulator and trivial insulator phases; a new topological phase (the axion insulator); and a half-integer quantum Hall state associated with the quantum parity anomaly. Furthermore, the author shows how these quantum phases can be significantly stabilized via magnetic modulation doping and proximity coupling with a normal ferromagnetic insulator. These findings provide a basis for future technologies such as ultra-low energy consumption electronic devices and fault-tolerant topological quantum computers.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5061SpintronicsTopological insulatorsSurfaces (Physics)SemiconductorsSolid state physicsSpintronicsTopological MaterialSurface and Interface and Thin FilmSemiconductorsElectronic DevicesSpintronics.Topological insulators.Surfaces (Physics)Semiconductors.Solid state physics.Spintronics.Topological Material.Surface and Interface and Thin Film.Semiconductors.Electronic Devices.530.41Mogi Masataka1228965MiAaPQMiAaPQMiAaPQ9910568258903321Quantized Phenomena of Transport and Magneto-Optics in Magnetic Topological Insulator Heterostructures2852972UNINA
