UAB researchers have developed a making method of magnetic elements with submicrometric dimensions more simple and economic than usuals. The process is to deform locally no magnetic material. These structures have many possible aplications: magnetic data storage systems, magnetic sensors, biomedical aplications or magnetoelectronic micro and...
