Among magnets, only ferromagnets have been used for applications, for example, as the main active materials for memory devices. On the other hand, antiferromagnets have attracted recent interest for designing next generation high-density and ultrafast devices because they produce no stray fields and have much faster dynamics. Here we introduce a new type of functional antiferromagnets with vanishingly small magnetization, namely, topological Weyl magnets that can be easily controlled by magnetic field, produce large responses, and thus could be useful for future applications including spintronics.
