Noncentrosymmetric cubic helical ferromagnets Mn1 − yFeySi and Fe1 − xCoxSi

Two systems of noncentrosymmetric cubic helical magnets Mn1 − yFeySi (y = 0.06, 0.08, 0.10) and Fe1 − xCoxSi (x = 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.50) have been compared. The concentration dependences of the critical temperature and magnetic field have been obtained using small-angle polarized-neutron scattering and analyzed in the framework of the Bak-Jensen model. It has been established that, among the two interactions that play the main role in these systems, i.e., the isotropic symmetric ferromagnetic exchange and the Dzyaloshinskii-Moriya isotropic antisymmetric interaction, the former interaction determines the critical temperature in the Mn1 − yFeySi system and the latter interaction determines this temperature in the Fe1 − xCoxSi system.

Controlling the Dzyaloshinskii-Moriya interaction to alter the chiral link between structure and magnetism forFe1−xCoxSi

Monosilicides of 3d-metals frequently show a chiral magnetic ordering with the absolute configuration defined by the chirality of the crystal structure and the sign of the Dzyaloshinskii-Moriya interaction (DMI). Structural and magnetic chiralities are probed here for Fe

Complex Chiral Modulations in FeGe Close to Magnetic Ordering

Si series and their mutual relationship is found to be dependent on the chemical composition. The chirality of crystal structure was previously shown to be governed by crystal growth, and the value of the DMI is nearly the same for all monosilicides of Fe, Co and Mn. Our findings indicate that the sign of the DMI in Fe
