Exchange Interactions and Curie Temperatures of 3D- and 2D-Ferromagnets
Effective exchange interactions in bulk ferromagnets as well as in magnetic overlayers on Cu(001) covered by a Cu-cap layer of varying thickness were determined from first principles by map** of correspondin...

Double-Electron Photoemission from Surfaces
A general theory of double-electron photoemission (DPE) from solid surfaces is sketched. Guided by the one-step model of single-electron photoemission (SPE), DPE can be related closely to SPE if the electronic...

Ab-initio theory of the CPP-magnetoconductance
The current-perpendicular-to-plane (CPP) magnetoconductance of a trilayer consisting of a spacer sandwiched between two ideal leads is described on anab initio level. We employ the transmission matrix formulation...
