Field-dependent spin chirality and frustration in V3 and Cu3 nanomagnets in transverse magnetic field. 2. Spin configurations, chirality and intermediate spin magnetization in distorted trimers

•Distorted spin configurations determine field behavior of the variable chiralities.•Distortions change spin chiralities, intermediate M12± and staggered magnetization.•Magnetizations, distorted vector and scalar chiralities are strongly correlated.•Distorted V3, Cu3 nanomagnets possess large vector chirality in the ground state in B⊥.•Chiralities and distortions in EPR, INS and NMR spectra were considered.

Correlated spin configurations, magnetizations, frustration, vector κ¯z and scalar χ¯ chiralities are considered for distorted V‾3, /Cu3/ anisotropic DM nanomagnets in transverse Bx‖X and longitudinal B‖Z fields. Different planar configurations in the ground and excited states of distorted nanomagnets in Bx determine different field behavior of the vector chiralities and the degenerate frustration in these states correlated with the M̲̃12±(Bx) intermediate spin (IS) magnetization which describes the S12 characteristics, χ=0. Distortion results in the reduced κ¯z<1 chirality in the ground distorted configuration and in the maximum κz=±1 in the excited states with the planar 120° configurations at avoided level crossing. In B‖Z, distorted longitudinal spin-collinear configurations are characterized by the reduced degenerate frustration, out-of-plane staggered and IS M̲̃12±(Bz) magnetizations, and in-plane toroidal moments, correlated with the κ¯z, χ¯ chiralities, χ¯=±|κ¯z|. The chiralities and IS magnetization in EPR, INS and NMR spectra are considered. The quantitative correlations describe variable spin chirality, frustration and field manipulation of chiralities in nanomagnets.
