dc.description.abstractThe solid solution of BaTiO<inf>3</inf>-BiFeO<inf>3</inf> (BTO-BFO) exhibits enhanced magneto-electric coupling compared to the widely explored BiFeO<inf>3</inf>. In this study, we examined BTO-BFO nanorod arrays (and films) ranging from 200 to 600 nm in height (and thickness) by employing second harmonic emission (SHE) and ferromagnetic resonance (FMR) measurements. We demonstrated a large enhancement in SHE in nanorod arrays compared to the films, which can be attributed to the high surface-to-volume ratio in the nanorod arrays. Our FMR measurements showed low effective damping parameters of (4-8) × 10<sup>−3</sup> in both nanorods and film structures. These observations are promising for future nonlinear optoelectronics and spintronics applications.en
