Magnetic Polarons in One-dimensional Antiferromagnetic Chains

Prilepsky, Jaroslaw; Kovalev, Alexander; Johansson, Magnus; Kivshar, Yuri

Description

We study magnetic polarons in antiferromagnetic chains by using the one-dimensional Anderson-Hasegawa double-exchange discrete model, and find analytically different families of magnetic polaron compactons. To study stability and nontrivial dynamics of the self-trapped magnetic polarons, we generalize the Anderson-Hasegawa model to allow for a finite spin of the lattice, and investigate different types of stationary states with collinear and canted spin structure, revealing the existence of...[Show more]
