1. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets
Sammanfattning : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. LÄS MER
2. Nanospintronics with Molecular Magnets - Tunneling and Spin-Electric Coupling
Sammanfattning : This dissertation investigates theoretically electric control of the magnetic properties of molecular magnets. Two classes of magnetic molecules are considered. The first class consists of molecules that are spin frustrated. LÄS MER
3. Characterization of Magnetic Nanoscale Systems: From Molecules to Particles and Self-Assembled Chains
Sammanfattning : This thesis characterizes magnetic nanoscale systems with increasing size and aspect ratio using synchrotron radiation-based spectroscopy and microscopy techniques, combined with conventional magnetometry. The systems studied are molecular magnets, bimagnetic nanoparticles and self-assembled magnetic nanochains. LÄS MER
4. Dynamics of Magnetic Molecules under Electrical Control
Sammanfattning : This thesis theoretically studies the dynamics of molecular magnets under electrical control. Molecular magnets are nanoscale magnets that can, e.g., consist of single-molecules or single-atoms. LÄS MER
5. Molecular Electronics : A Theoretical Study of Electronic Structure of Bulk and Interfaces
Sammanfattning : This thesis deals with theoretical studies of the electronic structure of molecules used in the context of molecular electronics. Both studies with model Hamiltonians and first principle calculations have been performed. LÄS MER
