Possible Definition Of Atom- And Bond-Resolved Contributions To The Magnetocrystalline Anisotropy Energy

Two notes on the interpretation of the magnetocrystalline anisotropy energy are given. First, methods to define atom-resolved contributions to the magnetocrystalline anisotropy energy of compounds are scrutinized. Second, a method concerning bond-resolved contributions is introduced which is able to test Kittel's famous interpretation of the magnetocrystalline anisotropy energy.
