Dataset associated with publication on skyrmion breathing modes in a synthetic ntiferromagnetic multilayer. All data was generated using the micromagnetic solver mumax3, studying the static behaviour of skyrmions as a function of applied magnetic field, and interlayer antiferromagnetic coupling strength. Also studied are the breathing modes of these skyrmions as a function of field, coupling strength structural disorder and temperature

Dataset Associated with Breathing Modes of Skyrmion Strings in a Synthetic Antiferromagnet

Skyrmions are small topologically protected magnetic structures that hold promise for applications from data storage to neuromorphic computing and they have been shown to possess internal microwave frequency excitations. Skyrmions in a synthetic antiferromagnet have been predicted to be smaller and faster than their ferromagnetic equivalents and also shown to possess more internal modes. In this work, we consider the breathing modes of skyrmions in a four repetition synthetic antiferromagnetic multilayer by means of micromagnetic simulations and examine the further splitting of the modes into different arrangements of out-of-phase, in-phase, and modes with more complex phase relationships. This results in a lowering of frequencies, which is promising for skyrmion sensing applications in a synthetic antiferromagnet

Breathing Modes of Skyrmion Strings in a Synthetic Antiferromagnet Multilayer

Skyrmions are small topologically protected magnetic structures that hold
promise for applications from data storage to neuromorphic computing and they
have been shown to possess internal microwave frequency excitations. Skyrmions
in a synthetic antiferromagnet have been predicted to be smaller and faster
than their ferromagnetic equivalents, and also shown to possess more internal
modes. In this work we consider the breathing modes of skyrmions in a four
repetition synthetic antiferromagnetic multilayer by means of micromagnetic
simulations and examine the further splitting of the modes into different
arrangements of out-of-phase and in-phase modes. This results in a lowering of
frequencies which is promising for skyrmion sensing applications in a synthetic
antiferromagnet.Comment: 6 pages, 4 figure
