Abstract

Magnetic susceptibility was studied of $Ca_2Fe_2-\timesMn\timesO5$ members crystg. in 2 different structures, one having octahedral (O), tetrahedral (T) and square-pyramidal (SP) coordination of transition metal atoms (OTSP structure) and the other having octahedral and tetrahedral coordination (OT structure). Susceptibility behavior of the oxides with OTSP structure is different from that of the oxides with OT structure. $Ca_2Fe1.33Mn0.67O5$ with OTSP structure shows an antiferromagnetic ordering while the corresponding oxide with OT structure shows weak ferromagnetism.
