We investigate the inverse scattering problem of the perturbed biharmonic operator by studying the recovery process of the magnetic field $ {\mathbf{A}} $ and the potential field $ V $. We show that the high-frequency asymptotic of the scattering amplitude of the biharmonic operator uniquely determines $ {\rm{curl}}\ {\mathbf{A}} $ and $ V-\frac{1}{2}\nabla\cdot{\mathbf{A}} $. We study the near-field scattering problem and show that the high-frequency asymptotic expansion up to an error $ \mathcal{O}(\lambda^{-4}) $ recovers above two quantities with no additional information about $ {\mathbf{A}} $ and $ V $. We also establish stability estimates for $ {\rm{curl}}\ {\mathbf{A}} $ and $ V-\frac{1}{2}\nabla\cdot{\mathbf{A}} $.

Keywords: Inverse scattering, bi-harmonic operators, Schrödinger operator, stability estimates, scattering amplitude, near-field scattering.
