José’s research focuses on developing a new variant of magnetic sensor based on the spin-orbit torque. These sensors take advantage of the spin-orbit interaction created at the interface between a ferromagnetic material and a heavy metal and the spin-Hall effect to, under a certain critical current on the heavy metal layer, inject a spin-current into the ferromagnetic layer allowing the linearity of the anomalous Hall resistance with the applied magnetic field. Due to the symmetry of a Hall Cross, the in-plane and out-of-plane signal can be distinguished allowing to detect the 3 components of a applied magnetic field using a single element.  He has been developing a micromagnetic model to predict the critical current of different heavy metal layers, complementing it with magnetic characterization of multilayer ultra-thin films in the SQUID MPMS and electrical characterization of Hall Crosses in the PPMS.
