  1. dagegen A-Typ-Ordnung (lagenartig). Der Grund liegt in der orbitalen Ordnung und den Goodenough-Anderson-Kanamori-Regeln. Die orbitale Ordnung entsteht aufgrund des kooperativen Jahn-Teller-Effekts. Zwischen den Ebenen sind jeweils zwei gleiche Orbitale benachbart. Für sie gilt der ganz

  2. For simple cases, the GoodenoughKanamori rules readily allow the prediction of the net magnetic exchange expected for the coupling between ions. Complications begin to arise in various situations: when direct exchange and superexchange mechanisms compete with one another; when the cation–anion–cation bond angle deviates away from 180°;

  3. 25. Mai 2022 · These rules, known as the Goodenough-Kanamori rules or sometimes the Goodenough-Kanamori-Anderson rules (GKA rules), determine the sign and strength of superexchange interactions between different orbitals. This article is organized as follows. The first section reviews the GKA rules. We report our recent investigation of CrI 3 /MoTe 2 /CrI 3 ...

  4. 4. Dez. 2019 · The magnetic ground states in highly ordered double perovskites LaSr1−xCaxNiReO6 (x = 0.0, 0.5, 1.0) are studied in view of the Goodenough-Kanamori rules of superexchange interactions in this paper.

  6. 12. Juni 2020 · Goodenough-Kanamori-Anderson rules (GKA rules) in superexchange interaction discriminate the magnetic properties of two magnetic metal ions bridged with an anion. We propose here that the GKA rules can be explained in terms of the orbital phase continuity-discontinuity property of cyclic orbital interaction including direct metal-metal orbital interaction.

  7. 4. Nov. 2022 · Goodenough's guidelines were complimented by a series of publications by Kanamori who refined his formalisms into a more rigorous mathematical context and together formed the empirical foundation of rules for understanding SE from the viewpoint of atomic bonding, electronic structure, and ligand field theory. These rules have been shown to validate the results of Anderson's rigorous ...
