These files are the data associated with the publication in Applied Physics Letters "Observation of spin-wave Doppler shift in Co90Fe10/Ru micro-strips for evaluating spin polarization" by Satoshi Sugimoto, Mark C. Rosamond, Edmund H. Linfield, and Christopher H. Marrows The files are Origin plots containing the figures and data needed to plot them, as follows: ##################################################################### Fig_1s.opj (a) Fourier transform of the microwave current density and (b) Typical resonant spectra of mutual inductance change ∆S_12. ##################################################################### Fig_2s.opj External field dependence of the main and secondary peak frequencies. ##################################################################### Fig_3_CF_final.opj Mutual inductance spectra in the presence of a positive dc current for Co90Fe10. ##################################################################### Fig_3_Py_final.opj Mutual inductance spectra in the presence of a positive dc current for Permalloy. ##################################################################### Fig_4_Py_CFs.opj k-normalised frequency shifts ∆f/k versus current density J for Permalloy and Co90Fe10 wires ##################################################################### Fig_5s.opj k-normalised frequency shifts ∆f versus current density J for Co90Fe10 (20), Ru (5) / Co90Fe10 (10), Ru (5) / Co90Fe10 (10) / Ru (5), Co90Fe10 (10) / Ru (5) wires
