The rotation behavior of the vector chirality κ, scalar chirality χ, and magnetization M in the rotating magnetic field H₁ is considered for the V₃ and Cu₃ nanomagnets, in which the Dzialoshinsky–Moriya coupling is active. The polar rotation of the field H₁ of the given strength H₁ results in the energy spectrum characterized by different vector and scalar chiralities in the ground and excited states. The magnetochiral correlations between the vector and scalar chiralities, energy, and magnetization in the rotating field were considered. Under the uniform polar rotation of the field H₁, the ground-state chirality vector κ_I performs sawtooth oscillations and the magnetization vector M_I performs the sawtooth oscillating rotation that is accompanied by the correlated transformation of the scalar chirality χ_I. This demonstrates the magnetochiral effect of the joint rotation behavior and simultaneous frustrations of the spin chiralities and magnetization in the rotating field, which are governed by the correlation between the chiralities and magnetization.
