Renormalization of Bulk Magnetic Electron States at High Binding Energies
A. Hofmann, X. Y. Cui, J. Schaefer +11
The quasiparticle dynamics of electrons in a magnetically ordered state is investigated by high-resolution angle-resolved photoemission of Ni(110) at 10 K. The self-energy is extra…
Spin-orbit coupling in ferromagnetic Nickel
J. Bünemann, F. Gebhard, T. Ohm +2
We use the Gutzwiller variational theory to investigate the electronic and the magnetic properties of fcc-Nickel. Our particular focus is on the effects of the spin-orbit coupling.…
Gutzwiller-Correlated Wave Functions: Application to Ferromagnetic Nickel
Joerg Buenemann, Florian Gebhard, Torsten Ohm +2
Ferromagnetic Nickel is the most celebrated iron group metal with pronounced discrepancies between the experimental electronic properties and predictions of density functional theo…
Atomic correlations in itinerant ferromagnets: quasi-particle bands of nickel
J. Buenemann, F. Gebhard, T. Ohm +11
We measure the band structure of nickel along various high-symmetry lines of the bulk Brillouin zone with angle-resolved photoelectron spectroscopy. The Gutzwiller theory for a nin…
Total Energy Studies for Ferromagnetic Nickel: What is the Optimum Combination of the Multi-band Gutzwiller Method and Density Functional Theory?
T. Ohm, S. Weiser, R. Umstätter +2
The multi-band Gutzwiller method, combined with calculations based on density functional theory, is employed to study total energy curves of the ferromagnetic ground state of Ni. A…
Quantum Hole Digging in Magnetic Molecular Clusters
W. Wernsdorfer, T. Ohm, C. Sangregorio +3
Below 360 mK, Fe8 magnetic molecular clusters are in the pure quantum relaxation regime. We showed recently that the predicted ``square-root time'' relaxation is obeyed, allowing u…
Observation of the distribution of molecular spin states by resonant quantum tunneling of the magnetization
W. Wernsdorfer, T. Ohm, C. Sangregorio +3
Below 360 mK, Fe magnetic molecular clusters are in the pure quantum relaxation regime and we show that the predicted square-root time relaxation is obeyed, allowing us to develop…
