Alkalimetallmanganchalkogenide : Synthese, Struktur und Magnetismus
Subject of this dissertation are the correlation between structure and magnetism of some Alkalimetal-Manganese-Chalcogenids. The compounds K2Mn3S4 and Rb2Mn3Te4 were synthesised and the structure were determined by single crystal X-Ray-Diffraction. The spin-structures of the compounds K2Mn3S4 and …

Chalkogenidlegierungen für optische und elektronische Speichermedien
Phasechange alloys are commonly used in optical data storage. Within the next few years an additional application of these alloys is expected to be in solid state memories. In contrast to their widespread use, an understanding of the underlying mechnisms is still incomplete. In this work the …

Quaternary Silver Bismuth Chalcogenide Halides Ag - Bi - Q - X (Q = S, Se; X = Cl, Br): Syntheses and Crystal Structures
Systematic synthetic investigations of the quaternary systems Ag - Bi - Q - X (Q = S, Se; X = Cl, Br) led to a variety of quaternary phases that exhibit considerable structural diversity with increasing complexity. These include Ag1.2Bi17.6S23Cl8, AgBi4Se5Br3 and numerous members of the homologous …

Halogen-, Azid- und Koordinationsverbindungen des Phosphors
… PCl3, PBr3, PI3 und P2I4 wie auch die Phosphor-Chalkogenide P4S3 und P4Se3 aufgrund ihrer schwachen Donoreigenschaft nur sehr schwachgebundene Spezies mit Elektronenacceptoren bilden. So sind die gebildeten Komplexverbindungen X3P⋅BY3 (X = Cl, Br, I; Y = Br, I) und (P4E3)⋅(BX3) (X = Br, I) wie …
