Abstract / Description:We study a two-dimensional effective orbital superexchange model
derived for strongly correlated e,, electrons coupled to t(2g) core
spins in layered manganites. One finds that the ferromagnetic (FM) and
antiferromagnetic (AF) correlations closely compete, and small changes
of parameters can switch the type of magnetic order. For the same
reason, spin order is easily destroyed with rising temperature, while
alternating orbital correlations can persist to temperatures where FM
order has already melted. A scenario for the AF phase observed in
LaSrMnO4 is presented. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA,
