Abstract
Possible mechanisms for the formation of long-period structure in the compound MnCoSi are considered. It is found that the main role in the theoretical treatment is played by invariants containing the first spatial derivative of the irreducible magnetic vectors to different powers. It is shown that in the formation of a spiral structure by only the antiferromagnetic vectors a spontaneous involvement of the ferromagnetic vector can occur, whereupon the orthogonality of the rotating vectors is broken. The analysis is carried out both with and without taking into account the approximate constancy of the moduli of the irreducible vectors. This makes it possible to consider the evolution of magnetic superstructure on changing temperature.
