Skyrmions in ferrimagnets
Abstract
Abstract In this chapter, we introduce the concept of magnetic skyrmions in ferrimagnetic materials. We also review and discuss recent findings and advances in the field of ferrimagnetic skyrmions. In particular, we focus on the theoretical and experimental works regarding the writing, deleting, imaging, and detection of ferrimagnetic skyrmions that are key ingredients for future applications. We also introduce and discuss the current-induced dynamics of ferrimagnetic skyrmions, including the associated skyrmion Hall effect in ferrimagnets. Finally, we briefly review potential applications based on ferrimagnetic skyrmions. The special fully compensated case of ferrimagnetic skyrmions, that is, the antiferromagnetic skyrmions, will be reviewed in detail in Chapter 10.
