Recently, a paper titled “Controlling bimerons as skyrmion analogues by ferroelectric polarization in 2D van der Waals multiferroic heterostructures” was published on Nature Communications. The work, done by PhD student Wei Sun, Professor Zhenxiang Cheng and Dr. Hang Li, was the new research result on exploring the novel properties of magneto-electric in 2D ferroelectric materials. The first author, Wei Sun, is the PhD student of the school of physics and electronics in Henan university.

Skyrmion is a novel topological spin structure with the advantage of a small size and stability as well as controllability. It was proposed to use for the new generation of electronic device and easy to record more dense information with a lower energy consumption. In bulk and multilayered structure, the skyrmion holds the rotational symmetry. The spins at the center in skyrmion rotate progressly from the center to the edge. In 2D magnetic materials LaCL and ferroelectric In2Se3 bilayered heterostructure, the skyrmion was suppressed by perpendicular magnetic anostropy and in the new form of bimeron. The transition can be controlled by electric field. The bimeron in 2D heterostructures can be transported by injected spin polarized current. This work theoretically confirms the creation and manipulation in 2D magnetic materials heterostructure.

The work was supported by National Natural Science Foundation of China and Henan university.
