Spin resolved photoelectron spectroscopy of oxidic half-metallic ferromagnets and oxide-ferromagnet interfaces
Spin- and angle-resolved photoelectron spectroscopy was applied to study the spin-dependent electronic structure of the half-metallic ferromagnetic materials (Fe3O4 and CrO2) and bilayers I/FM (I = Al2O3 or MgO, FM = Fe(110)). Fe3O4 and CrO2 are found to be consistent with half-metallic …

Ferromagnetism of novel ultrathin films and multilayers: A study of Ru/C(0001) and Fe/Mn/Fe/Pd(100) using magneto-optic Kerr effect and spin-sensitive electron spectroscopies
… surface is studied using electron induced spin-polarized secondary electron emission (SPSEE). Below a surface Curie temperature of approximately 250K we find ferromagnetic order of the Ru monolayer. The growth mode of Ru on C(0001) is investigated by Auger electron spectroscopy (AES). We …

Time, momentum, spin, and energy resolved tunneling spectrum of a two-dimensional electron system
… that can visualize the energy, momentum, spin, and time resolved electronic structures of 2D electronic systems. Unlike the conventional tunneling method that requires the in-plane conductivity of the system, our pulsed tunneling technique functions on strongly insulating systems at low …

Control of chiral optical and spin properties in low-dimensional perovskites
… symmetry breaking, giving rise to spin-selective and circularly polarized optical phenomena. The introduction of chiral organic cations breaks inversion and mirror symmetries and induces unique structural behavior in the absence of external magnetic fields, e.g., circularly …

Photoemission Spectroscopy Studies of New Topological Insulator Materials
… state in which the orientation of the electron’s spin is locked perpendicular to its momentum. This property suppresses backscattering (making it possible to pass spin-polarized currents through the material without loss), offers a crucial ingredient for innovative approaches to quantum …

A photoemission study of quasiparticle excitations, electron-correlation effects and magnetization dynamics in thin magnetic systems
This thesis is focused on the electronic, spin-dependent and dynamical properties of thin magnetic systems. Photoemission-related techniques are combined with synchrotron radiation to study the spin-dependent properties of these systems in the energy and time domains. In the first part of this …
