摘要： Compared with ferromagnets, antiferromagnets hold huge potential in high-density information storage because of their ultrafast spin dynamics and vanishingly small stray field. Here we investigate the electrical detections and manipulations of antiferromagnetic moments, which might pave an alternative way towards new-generation spin memory devices.
