Some Model Systems. Internal Structure of Magnetic Polarons
摘要
We consider different anisotropic doped antiferromagnets on regular and frustrated (triangular) lattices and determine the optimum shape and volume of the magneticInteractionCoulomb droplets (mainly of the ellipsoidal type) in them. We also consider magnetic polarons bound byCoulomb interactionwith impurity Coulomb interaction with the impurity (Sr ion) and a long-range coat of spin distortions produced by them.
