Investigating the skyrmion breathing mode using conjugate variables — •Benjamin F. McKeever1, Artem G. Abanov2, and Karin Everschor-Sitte1 — 1Johannes Gutenberg-Universität, Mainz, Germany — 2Texas A&M University, College Station, Texas, USA
The understanding and subsequent manipulation of properties of magnetic skyrmions is an important challenge for their use in future energy-efficient devices. Different excitations of single skyrmions have been observed and here we consider the so called “breathing mode” in which the core region of the skyrmion periodically grows and shrinks. We analyse the breathing mode in analogy to how it has been studied in quantum Hall systems, namely by using a phenomenological theory of conjugate variables.
