Experimental data on magnetization of the antiferromagnetic (AFM) polycrystalline samples in the temperature range of 20–300 K, for pressures of 2 kbar and in magnetic field of 300 kOe, are presented in the paper. In the fields of 250 kOe, the magn

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 magne

It is shown that incommensurate long-period structures formed by two synchronously rotating irreducible magnetic vectors are unstable and split into two interacting superstrucures. The behavior of such states away from and close to the phase-transiti

The distribution of magnetization in domain walls of ferromagnetic (FM) crystals with two order parameters interacting with each other— F 1 z and F 2 z , is considered. In one case the interaction is represented as ( F 1 z F 2 z ) and in another—

The formation of superstructures due to the interaction of one-component and two-component order parameters in three-sublattice magnets is considered. It is shown that, in the general case, the propagation vector is located in the XOY plane and the i

The formation of superstructures is considered with allowance for the biquadratic exchange interaction. It is shown that in this case the simultaneous coexistence of several long-period structures is possible, which can arise as a result of a first-

The possibility of formation of a long-period structure in crystals with triangular arrangement of magnetic atoms is considered. It is shown that two cycloid and one spiral structures are formed. The influence of a magnetic field and second-order mag

Possible mechanisms of the formation of a long-period structure in the MnCoSi compound are considered. It is established that the invariants containing the first spatial derivative of the irreducible magnetic vectors in different powers play a key ro
