The Löwdin orthogonalization and magnetoelectric coupling for noncentrosymmetric ions
arXiv:1409.5084 · doi:10.26907/mrsej-19409
Abstract
The Loewdin orthogonalization procedure being the well-known technique, particularly in quantum chemistry, however, gives rise to novel effects missed in earlier studies. Making use of the technique of irreducible tensorial operators we have developed a regular procedure for account of the orthogonalization effects. For illustration we address the emergence of a specific magnetoelectric coupling for noncentrosymmetric 3d or 4f ions.
