Absence of ferromagnetism in Mn- and Co-doped ZnO

, 2004
Following the theoretical predictions of ferromagnetism in Mn- and Co-doped ZnO, several workers reported ferromagnetism in thin films as well as in bulk samples of these materials.

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

, 2007
In order to resolve the long-standing issue of how the itinerant ferromagnetism is affected by the lattice structure and Hund's coupling, we have compared various three-dimensional lattice structures in the single- and multiorbital Hubbard models with ...

Itinerant ferromagnetism in a two-dimensional atomic gas

, 2010
Motivated by the first experimental evidence of ferromagnetic behavior in a three-dimensional ultracold atomic gas, we explore the possibility of itinerant ferromagnetism in a trapped two-dimensional atomic gas.

Theory of carrier mediated ferromagnetism in dilute magnetic oxides

, 2006
We analyze the origin of ferromagnetism as a result of carrier mediation in diluted magnetic oxide semiconductors in the light of the experimental evidence reported in the literature.

Coexistence and competition of ferromagnetism and p-wave superconductivity in holographic model

, 2014
By combining a holographic p-wave superconductor model and a holographic ferromagnetism model, we study the coexistence and competition of ferromagnetism and p-wave superconductivity.

A theory of ferromagnetism by Ettore Majorana

, 2008
We present and analyze in detail an unknown theory of ferromagnetism developed by Ettore Majorana as early as the beginnings of 1930s, substantially different in the methods employed from the well-known Heisenberg theory of 1928 (and from later ...

Origin of room-temperature ferromagnetism in Mn doped semiconducting CdGeP2

, 2001
CdGeP2 chalcopyrites doped with Mn have been recently found to exhibit room temperature ferromagnetism. Isovalent substitution of the Cd site is expected, however, to create antiferromagnetism, in analogy with the well-known CdTe:Mn (d^5) case.

Field Effect Magnetization Reversal in Ferromagnetic Semiconductor Quantum Wells

, 2001
We predict that a novel bias-voltage assisted magnetization reversal process will occur in Mn doped II-VI semiconductor quantum wells or heterojunctions with carrier induced ferromagnetism.
