CaCuMn6o12 vs. CaCu2Mn5O12: a comparative study

摘要

The ferrimagenetic compounds Ca(CuxMn3-x)Mn4O12 is driven by strong antiferromagnetic exchange nteraction of (Cu2+)c with octahedra coordinated (Mn3+/4+)B. The competing interactions of (Mn3+)c with (Mn3+/4+)B lead to the formation of non-collinear magnetic structures which can be aligned by magnetic field.
