Discussion: Terms of the spin Hamiltonian

[adrybakov]

Topic: What terms should be supported by the file format.?

[adrybakov]

Here is the list of the terms that have been mentioned in the summary or surveys:

• Linear interactions
  • Zeeman term
• Bi-linear interactions
  • Scalar isotropic Heisenberg exchange
  • Antisymmetric exchange (i. e. Dzyaloshinskii-Moriya interaction)
  • Symmetric anisotropic exchange (traceless part of the symmetric part of the full 3x3 matrix)
  • Quadratic on-site anisotropy
  • Classical magnetic dipole-dipole interaction
• Quad-linear interactions
  • Bi-quadratic exchange interaction
  • Quartic on-site anisotropy
• n-linear interactions
• Uniaxial, rotational, and cubic anisotropies up to the 6th order
• Crystal field parameters
• Magneto-elastic interaction

P. S. The micro-magnetic Hamiltonian is not mentioned here.
