Confined Spin Waves in a Bulk Chiral Magnet with DMI Interaction

Raw data from a combined experimental and micromagnetic modeling study of confined dipole and exchange spin waves in the chiral magnet Cu2OSeO3. The data supports a manuscript investigating the impact of the Dzyaloshinskii-Moriya interaction on spin wave dispersion and the observation of confined spin waves up to the eleventh order. The work was supported by the Swiss National Science Foundation, the Deutsche Forschungsgemeinschaft, and the European Research Council.

Use Cases

• Analyzing asymmetry in spin wave dispersion relations based on the Dzyaloshinskii-Moriya interaction mentioned in the description
• Modeling confined eigenmodes and spin wave spectra based on micromagnetic simulation data
• Studying the simultaneous excitation of dipole- and exchange-dominated spin waves with wavelengths down to ~47 nm
• Validating experimental broadband microwave spectroscopy results with simulation outputs

Strengths

• Data is associated with a peer-reviewed manuscript, providing academic context
• Includes results from both experimental spectroscopy and micromagnetic modeling, offering a combined perspective
• Describes observation of confined spin waves up to the eleventh order

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
