Summary : Louis Neel, who received Nobel Prize in Physics 1970 for his pioneering work on magnetic properties of solids, commented in his Nobel lecture that "They (antiferromagnets) are extremely interesting from the theoretical viewpoint, but do not seem to have any applications." More than 40 years after his winning the prize, now antiferromagnets seem to be finally finding their major applications in the field of spintronics; people are realizing that replacing ferromagnets involved in spintronic devices by antiferromagnetic materials can lead to downsizing of the devices as well as much faster operations. One of the difficulties in dealing with antiferromagnetic materials, however, comes from the absence of macroscopic magnetization, making it hard to control them by magnetic fields. In this talk, we will discuss two phenomena, spin-transfer torque and spin-motive force, which could provide a route to generate and detect dynamical antiferromagnetic textures by electrical means.
