Spin Chirality of Cu-3 and V-3 Nanomagnets. 2. Frustration, Temperature, and Distortion Dependence of Spin Chiralities and Magnetization in the Rotating and Tilted Magnetic Fields
We consider the frustration, magnetochiral correlations, temperature and distortion dependences of the vector and scalar chiralities, magnetization, and orbital angular momentum of the Cu-3 and V-3 nanomagnets in the rotating magnetic field, as well as the spin chiralities and frustration in the tilted magnetic field, the joint frustrated rotation behavior of the correlated spin chiralities and magnetization. Spin chiralities and magnetization demonstrate strong frustration in the rotating and tilted magnetic fields. An increase of the temperature and trimer distortions results in the reduction of the chiralities and frustration. The equilateral and distorted clusters with large Dzialoshinsky-Moriya (DM) parameters are characterized by the large spin chirality. An increase of the strength of the tilted magnetic field H-zeta leads to the inhomogeneous polar rotation of the chirality and magnetization vectors, which depends on the temperature.
