Role of the Dzyaloshinskii-Moriya interaction in multiferroic perovskites
I. A. Sergienko, E. Dagotto
With the perovskite multiferroic RMnO3 (R = Gd, Tb, Dy) as guidance, we argue that the Dzyaloshinskii-Moriya interaction (DMI) provides the microscopic mechanism for the coexistenc…
The One-Particle Spectral Function and the Local Density of States in a Phenomenological Mixed-Phase Model for High-Temperature Superconductors
M. Mayr, A. Gonzalez, A. Moreo +1
The dynamical properties of a recently introduced phenomenological model for high temperature superconductors are investigated. In the clean limit, it was observed that none of the…
Phase Diagram of the Two-Leg Kondo Ladder
J. C. Xavier, E. Miranda, E. Dagotto
The phase diagram of the two-leg Kondo ladder is investigated using computational techniques. Ferromagnetism is present, but only at small conduction electron densities and robust…
Insulator to Metal Transition Induced by Disorder in a Model for Manganites
C. Sen, G. Alvarez, E. Dagotto
The physics of manganites appears to be dominated by phase competition among ferromagnetic metallic and charge-ordered antiferromagnetic insulating states. Previous investigations…
Open Questions in CMR Manganites, Relevance of Clustered States, and Analogies with other Compounds
Elbio Dagotto
This is an informal paper that contains a list of ``things we know'' and ``things we do not know'' in manganites. It is adapted from the conclusions chapter of a recent book by the…
Theory of Manganites
Takashi Hotta, Elbio Dagotto
In this review, the present status of theories for manganites is discussed. The complex phase diagrams of these materials, with a variety of spin-charge-orbital ordering tendencies…
