radtools.ExchangeHamiltonian.summary_as_txt

method

ExchangeHamiltonian.summary_as_txt(template: ExchangeTemplate, decimals=4, force_symmetry=False, isotropic=False, anisotropic=False, matrix=False, dmi=False)

Return exchange Hamiltonian based on the template file in .txt format.

Parameters:

templateExchangeTemplate

Template of the desired exchange Hamiltonian. (see rad-make-template.py)

accuracyint, default 4

Accuracy for the exchange values

force_symmetry: bool, default False

Whether to force the symmetry of the template on the exchange Hamiltonian. If False then each individual bond is written, otherwise exchange parameters of the template are written.

isotropicbool, default False

Whether to output isotropic exchange.

anisotropicbool, default False

Whether to output anisotropic exchange.

matrixbool, default False

Whether to output whole matrix exchange.

dmibool, default False

Whether to output DMI exchange.

Returns:

summarystr

Exchange information as a string.
