(Top) Example of the system developed: a ferromagnetic material that can generate a spin current and inject it into an interface material, in which it is converted into a charge current. Traditionally, in order to change the sign of the charge current produced, the magnetization of the ferromagnetic material must be reversed by applying a magnetic field or a powerful current. Here this is produced by reversing the polarisation of the ferroelectric material using an electric field. (Bottom) Experimental curve showing the evolution of the charge produced as a function of the voltage applied to the ferroelectric material.
