|Abstract:||Neutron diffraction study as a function of temperature on the bilayered manganite Ca2.5Sr0.5GaMn2O8
has revealed antiferromagnetic correlations between the  oriented Mn spins in the a-c plane. Three-dimensional (3D) short-range and two-dimensional (2D) long-range order over the temperature ranges 180–170K and 165–160K , respectively, have been observed. Below ˜150K , a pure 3D long-range ordering has been observed. Finally a phase diagram is proposed. A qualitative connection is made between the 2D and 3D magnetic ordering to the transport and magnetotransport properties reported for this system.|
