Structural and magnetic instabilities of layered magnetic systems
Carsten Aits, Ute Löw, Andreas Klümper +1
We present a study of the magnetic order and the structural stability of two-dimensional quantum spin systems in the presence of spin-lattice coupling. For a square lattice it is s…
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…
NaV_2O_5 as a quarter-filled ladder compound
H. Smolinski, C. Gros, W. Weber +4
A new X-ray diffraction study of the one-dimensional spin-Peierls compound α-NaV_2O_5 reveals a centrosymmetric (Pmmn) crystal structure with one type of V site, contrary to the pr…
