magnopy.Energy.optimize#

method

Energy.optimize(initial_guess=None, energy_tolerance=1e-05, torque_tolerance=1e-05, quiet=False)[source]#

Optimize classical energy by varying the directions of spins in the unit cell.

Parameters:

initial_guess(M, 3) or (3,) array-like, optional: Initial guess for the direction of the spin vectors.
energy_tolerancefloat, default 1e-5: Energy tolerance for the two consecutive steps of the optimization. In the units of meV.
torque_tolerancefloat, default 1e-5: Torque tolerance for the two consecutive steps of the optimization. In the units of meV.
quietbool, default False: Whether to suppress the output of the progress.

Returns:

optimized_directions(M, 3) numpy.ndarray: Optimized direction of the spin vectors.
