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

Artificial Construction of the Layered Ruddlesden–Popper Manganite La2Sr2Mn3O10 by Reflection High Energy Electron Diffraction Monitored Pulsed Laser Deposition

“…Moritomo et al were unable to produce single crystals of (SrO)­(LSMO) 3 . High pressure synthesis has been attempted, but yielded a mixture of products. , Bulk synthesis of two (SrO)­(LSMO) 3 phases was reported, but no details of structural parameters or phase purity were given. , An alternative to A site doping is electron doping of Ca 4 Mn 3 O 10 by introduction of pentavalent ions onto the B site, which has successfully introduced ferromagnetism into these compounds, although B site substitution will naturally have an additional effect on the magnetic interactions. , It appears that it is very challenging to produce phase pure samples of n = 3 manganite phases in general, and (SrO)­(LSMO) 3 in particular through standard bulk synthesis methods. Furthermore, our attempts at ceramic synthesis of the RP3 composition studied here failed to yield the desired product.…”
