    The mechanisms of plastic deformation of glassy solids and structural origin of β relaxation are two fundamental issues. We provide compelling experimental evidence that the activation of shear transformation zones (STZs) and β relaxations in metallic glasses are directly related, and the activation energy of the β relaxation and the potential-energy barriers of STZs are nearly equivalent. Our results suggest an intrinsic correlation among potential STZs, β relaxation, and the inhomogeneous atomic structure of metallic glasses, which has implications for understanding the deformation mechanism and structural origin of β relaxation in glasses.
