      abstract     = {The short-range-ordered magnetic correlations have been
                      studied in half-doped La0.5Ca0.5-xSrxMnO3 (x=0.1, 0.3, and
                      0.4) compounds by polarized neutron scattering technique. On
                      doping Sr2+ for Ca2+ ion, these compounds with x=0.1, 0.3,
                      and 0.4 exhibit CE-type, mixture of CE-type and A-type, and
                      A-type antiferromagnetic ordering, respectively. Magnetic
                      diffuse scattering is observed in all the compounds above
                      and below their respective magnetic ordering temperatures
                      and is attributed to magnetic polarons. The correlations are
                      primarily ferromagnetic in nature above T-N, although a
                      small antiferromagnetic contribution is also evident.
                      Additionally, in samples x=0.1 and 0.3 with CE-type
                      antiferromagnetic ordering, superlattice diffuse reflections
                      are observed indicating correlations between magnetic
                      polarons. On lowering temperature below T-N, the diffuse
                      scattering corresponding to ferromagnetic correlations is
                      suppressed and the long-range-ordered antiferromagnetic
                      state is established. However, the short-range-ordered
                      correlations indicated by enhanced spin-flip scattering at
                      low Q coexist with long-range-ordered state down to 3 K. In
                      x=0.4 sample with A-type antiferromagnetic ordering,
                      superlattice diffuse reflections are absent. Additionally,
                      in comparison to x=0.1 and 0.3 sample, the enhanced
                      spin-flip scattering at low Q is reduced at 310 K, and as
                      temperature is reduced below 200 K, it becomes negligibly
                      low. The variation in radial correlation function, g(r) with
                      temperature indicates rapid suppression of ferromagnetic
                      correlations at the first nearest neighbor on approaching
                      T-N. Sample x=0.4 exhibits growth of ferromagnetic phase at
                      intermediate temperatures (similar to 200 K). This has been
                      further explored using small-angle neutron scattering and
                      neutron depolarization techniques.},
