(color online) Angular dependence of spin wave behaviors obtained in LSMO5/PMN-PT multiferroic heterostructures at 173 K at various applied voltages when the H-fields angles were (a) 60°, (b) 70°, (c) 80°, and (d) 90°, respectively. Arrows indicate the variation trend of the SWR spectra relative to the applied voltage.^[80]
