N2 - The low temperature adiabatic magnetization of the nanoscopic V15 cluster exhibiting a triangular spin-frustrated V3IV array is analyzed within the model that includes isotropic exchange interactions and antisymmetric (AS) exchange. Along with the absolute value of AS exchange the orientation of the AS vector is shown to play an important physical role in the spin-frustrated systems. We were able to reach a perfect fit to the experimental data on the stepwise magnetization vs. field in the whole temperature range and for the first time to estimate precisely two components of the AS vector, namely, in-plane and the perpendicular parts.
