Recently, the research team led by Song Cheng and Pan Feng from the School of Materials/Key Laboratory of Advanced Materials, Ministry of Education, at Tsinghua University, has achieved a notable breakthrough in the field of spintronics materials and devices. They have successfully demonstrated complete and efficient electrical switching of chiral antiferromagnetic order under zero magnetic field conditions.

By designing a homojunction structure, the team leveraged unconventional spin currents to induce unique magnetic dynamics within the chiral antiferromagnetic system. This innovative approach enabled precise electrical control over the magnetic order without the need for an external magnetic field, significantly enhancing operational efficiency.

This milestone not only paves the way for next-generation magnetic storage technologies but also offers valuable scientific insights for the development of terahertz nano-oscillators and rectifiers. The findings have been published in the prestigious journal Nature.
