This study discusses the magnetic oxide/heavy metal oxide hybrid film on a substrate with high dielectric constant, using the double exchange model to describe the system behavior. The interface between the two oxide films generates a unique Rashba spin-orbit interaction, resulting in phase separation in the magnetic film. The combination of phase separation and spin-orbit coupling leads to the formation of electrically charged magnetic clusters with skyrmions, where suitable cluster sizes for skyrmion formation only occur on a substrate with a high dielectric constant.
We consider magnetic oxide/heavy metal oxide hybrid film on top of a substrate with high dielectric constant. We use the double exchange model to describe the system behavior. The interface between two oxide films produces Rashba spin-orbit interaction. The phase separation appears in such a magnetic film. Combination of the phase separation and spin-orbit coupling leads to formation of electrically charged magnetic clusters with skyrmions. We show that such clusters have both electrical and topological charges. Importantly, clusters with sizes suitable for skyrmions formation may occur only for substrate with a high dielectric constant.
