چکیده

We introduce a novel mechanism for itinerant ferromagnetism, which is based on a simple two-band model, and, by using numerical and analytical methods, we show that the periodic Anderson model contains this mechanism. We propose that the mechanism, which does not assume an intra-atomic Hund's coupling, is present in both the iron group and some f electron compounds.

Theory on the Itinerant Ferromagnetism in the 3d-transition metal systems

Keeping nickel, cobalt and iron in mind, we investigate the origin of the itinerant ferromagnetism. Recent experiments show that the systems should be in an intermediate coupling regime, where the band width and the interaction energy are of the same order of magnitudes. To treat such a situation, we generalize the Gutzwiller approximation. In that, we take account of the effect of the band deg...

Microscopic conditions favoring itinerant ferromagnetism

A systematic investigation of the microscopic conditions stabilizing itinerant ferromagnetism of correlated electrons in a single-band model is presented. Quantitative results are obtained by quantum Monte Carlo simulations for a model with Hubbard interaction U and direct Heisenberg exchange interaction F within the dynamical mean-field theory. Special emphasis is placed on the investigation o...

Itinerant ferromagnetism in the multiorbital Hubbard model: a dynamical mean-field study.

In order to resolve the long-standing issue of how itinerant ferromagnetism is affected by lattice structure and Hund's coupling, we compare various three-dimensional lattice structures in the single- and multiorbital Hubbard models with the dynamical mean-field theory with an improved quantum Monte Carlo algorithm that preserves the spin-SU(2) symmetry. The result indicates that both the latti...

Metallic Ferromagnetism - an Electronic Correlation Phenomenon

New insights into the microscopic origin of itinerant ferromagnetism were recently gained from investigations of electronic lattice models within dynamical meanfield theory (DMFT). In particular, it is now established that even in the one-band Hubbard model metallic ferromagnetism is stable at intermediate values of the interaction U and density n on regular, frustrated lattices. Furthermore, b...

Itinerant ferromagnetism in a Fermi gas of ultracold atoms.

Can a gas of spin-up and spin-down fermions become ferromagnetic because of repulsive interactions? We addressed this question, for which there is not yet a definitive theoretical answer, in an experiment with an ultracold two-component Fermi gas. The observation of nonmonotonic behavior of lifetime, kinetic energy, and size for increasing repulsive interactions provides strong evidence for a p...
