Correlation Effects in Orbital Magnetism
Tor Jonas Sjöstrand, Krister Karlsson, Ferdi Aryasetiawan
Orbital magnetization is known empirically to play an important role in several magnetic phenomena, such as permanent magnetism and ferromagnetic superconductivity. Within the rece…
Dynamically screened Coulomb interaction in the parent compounds of hole-doped cuprates, trends and exceptions
Fredrik Nilsson, Krister Karlsson, Ferdi Aryasetiawan
Although the cuprate high-temperature superconductors were discovered already 1986 the origin of the pairing mechanism remains elusive. While the doped compounds are superconductin…
Electronic structure of (Ga,Mn)As revisited
J. Kanski, L. Ilver, K. Karlsson +4
The detailed nature of electronic states mediating ferromagnetic coupling in dilute magnetic semiconductors, specifically (Ga,Mn)As, has been an issue of long debate. Two confronti…
Green function theory of orbital magnetic moment of interacting electrons in solids
F. Aryasetiawan, K. Karlsson, T. Miyake
A general formula for the orbital magnetic moment of interacting electrons in solids is derived using the many-electron Green function method. The formula factorizes into two parts…
Electronic structure of (Ga,Mn)As revisited: an alternative view on the "Battle of the bands"
J. Kanski, L. Ilver, K. Karlsson +3
New detailed angle-resolved photoemission data are presented, revealing the existence of an Mn-induced state that extends into the band gap of GaAs. In sharp contrast to recent rep…
Effects of non-uniform Mn distribution in (Ga,Mn)As
I. Ulfat, J. Kanski, L. Ilver +3
Resonant in situ photoemission from Mn 3d states in Ga_{1-x}Mn_{x}As is reported for Mn concentrations down to very dilute limit of 0.1 at %. The properties of the peak at the vale…
