Superconductors – metals in which electricity flows without resistance – hold promise as the defining material of the near future, according to physicist Brad Ramshaw, and are already used in medical ...
The European Conference PHYSICS OF MAGNETISM 2017 (PM'17) will be held on June 26-30 in Poznań, Poland. The current event is going to be the fifteenth in a series which started in 1975. The conference...
By showing that a phenomenon dubbed the “inverse spin Hall effect” works in several organic semiconductors – including carbon-60 buckyballs – University of Utah physicists changed magnetic “spin curre...
09.05.14 - An EPFL-led research collaboration has shown for the first time the maximum theoretical limit of energy needed to control the magnetization of a single atom. The fundamental work can have g...

Twisted Hubbard Model for Sr2IrO4: Magnetism and Possible High Temperature Superconductivity
Twisted Hubbard Model for Sr2IrO4 Magnetism Possible High Temperature Superconductivity
2010/11/23
Sr2IrO4 has been suggested as a Mott insulator from a single Jeff = 1/2 band, similar to the
cuprates. However this picture is complicated by the measured large magnetic anisotropy and
ferromagnetis...

We employ x-ray spectroscopy to characterize the distribution and magnetism of particular alloy
constituents in (Ga,Fe)N films grown by metal organic vapor phase epitaxy. Furthermore, photo-
electro...
