property
- property ExchangeParameter.aniso: ndarray#
3 x 3 matrix of symmetric anisotropic exchange.
[[J_xx, J_xy, J_xz], [J_xy, J_yy, J_yz], [J_xz, J_yz, J_zz]]
Derived from the exchange matrix (\(\mathbf{J}\)) as
\[\mathbf{J}_{aniso} = \mathbf{J}_{symm} - \dfrac{1}{3}Tr(\mathbf{J}) \cdot \mathbf{I}\]where \(\mathbf{I}\) is a \(3\times3\) identity matrix.
- Returns:
- aniso(3, 3) numpy.ndarray
Matrix of symmetric anisotropic exchange.
