Magnetic ordering in the layered oxyselenides Sr2CoO2Ag2Se2 and Ba2CoO2Ag2Se2

Abstract:

The antiferromagnetic structures of Sr2CoO2Ag2Se2 and Ba2CoO2Ag2Se2 are solved using powder neutron diffraction. Both compounds adopt the same magnetic structure, based on a √2a × √2a × c expansion of the nuclear cell with magnetic space group PC42/n (86.72 in the Belov-Neronova-Smirnova notation). This structure is adopted as a result of nearest-neighbour antiferromagnetic interactions within the CoO2 planes. The refined long-range-ordered magnetic moments of Sr2CoO2Ag2Se2 and Ba2CoO2Ag2Se2 ...
