Goodenough-Kanamori-Anderson Rules in CrI<sub>3</sub>/MoTe<sub>2</sub>/CrI<sub>3</sub> Van der Waals Heterostructure
Meng‐Chien Wang, Ching‐Ray Chang
Abstract
Superexchange interaction is the main mechanism for spin ordering in magnetic insulators. Goodenough-Kanamori-Anderson(GKA) rules for superexchange interactions are widely applied in magnetic materials, including magnetic oxides, perovskites and recently discovered 2D vdW magnetic systems. We review GKA rules and its application in the first part of this article. In the second part, we investigate the interlayer magnetic coupling in CrI 3 /MoTe 2 /CrI 3 heterostructure using first principle calculation. The calculation result is discussed based on GKA rules.
