Piezostrain-enabled magnetization switching in magnetic/piezoelectric heterostructures consists of multiple coupled kinetic processes that have rarely been considered together, thus an accurate computational analysis on the switching speed has remained outstanding. Here a computational approach is developed to accurately analyze the speed of such piezostrain-enabled magnetization switching by linking local elastodynamics in the piezoelectric to local magnetization dynamics in the magnet. For example, the approach is utilized to analyze the speed of a recently proposed scheme of piezostrain-enabled 180° perpendicular magnetization switching, where the overall switching time is shown to be below 10 ns in a model CoFeB/Pb(Zr,Ti)O3 heterostructure.
