Soon there appeared works devoted to the study of high-entropic oxide systems with a more complex crystal structure.
The authors of [16-19] presented the results of the high-entropy phases creation with a perovskite structure.
A multicomponent (high-entropy) oxide phase with a spinel structure was obtained in [20].
It was assumed that the formation of phases with the structure of M-type hexaferrites is most likely for these systems.

On MS system is possible to evaluate the main molecules leaving the structure.
Therefore, for comparison, used and not used structures were analyzed.
In order to verify the reproducibility of these structures several pulses were inserted.
For some structures pulses of 2-propanol were alternated with n-hexane.
