A comparative analysis of the copper and iron ions bonds exchange energies was conducted for various variants of orderings and distributions of iron ions among crystallographic positions in ludwigite Cu{sub 2}FeBO{sub 5}. Analysis showed that the exchange bonds of iron ions play a key role in the formation of magnetic order. The magnetic ordering strongly depends on the distribution of iron ions among the positions. In the case when the Fe{sup 3+} is in the same position as in Fe{sub 3}BO{sub 5}, the most favorable magnetic structure is similar to the magnetic structure of ludwigite Fe{sub 3}BO{sub 5}. In other cases, the type of magnetic ordering is different.
