magnopy.Energy.torque#
method
- Energy.torque(spin_directions, units='meV', _normalize=True)[source]#
Computes torque on each spin.
- Parameters:
- spin_directions(M, 3) array-like
Directions of spin vectors. Only directions of vectors are used, modulus is ignored.
Mis the amount of magnetic atoms in the Hamiltonian. The order of spin directions is the same as the order of magnetic atoms inspinham.magnetic_atoms.spins.- unitsstr, default "meV"
Added in version 0.3.0.
Units of energy. See Units of energy for the full list of supported units.
- _normalizebool, default True
Whether to normalize the spin_directions or use the provided vectors as is. This parameter is technical and we do not recommend to use it at all.
- Returns:
- torque(M, 3) numpy.ndarray
[[t1x, t1y, t1z], [t2x, t2y, t2z], ...[tMx, tMy, tMz]]
