Recently, XJTU Professor Liu Ming, expert of the "Thousand Youth Talents Plan",and his team members from the School of Electronic and Information Engineering, carriedout research on flexible spintronic devices controlled by an electric field, and realized the visualization of domain rotation. This result, for the first time, developed a magnetoelectric coupling effect from flat to flexible curve research, perfectly filling in the gap of magneto-electric composite technology in the flexible spintronic electric field.
