Hello, I have a question concerning antisymmetric exchange in triangular trimers with three S=1/2 ions. The Hamiltonian for the antisymmetric exchange should be H=G[(S1xS2)+(S2xS3)+(S3xS1)]. Apparently Easyspin calculates the matrix elements and energy levels with the last term (S3xS1) replaced by (...
