Synthesis and atom-scale microstructure of Ba6Mn5O16

A superstructure modulation induced by La doping of the layered manganate LaxSr4−xMn3O10

“…Higher members of the hexagonal series, such as Ba 6 Mn 5 O 16 (n = 5) [14,15], have also been stabilized. These hexagonal layered manganates were revealed by the magnetic measurements to be antiferromagnetic (AFM) insulators [11,12,[14][15][16]. Up to now, despite many studies of the layered manganates belonging to the hexagonal series, little work has been concerned with the effects of doping by rare-earth elements.…”
