In the domain of spintronics, the class of compensated magnets, encompassing both non-collinear and collinear systems, attracts attention. Over the last two decades, researchers have gained insights into these materials, many of which were once deemed the exclusive domain of ferromagnets. In this talk, I will summarize the advantages offered by compensated magnets, shedding light on the remarkable advancements achieved in this field. Non-collinear antiferromagnets play a pivotal role for antiferromagnetic spintronics, and I will provide a brief overview of their significance.
Furthermore, I will focus on collinear compensated magnets characterized by unique crystal and spin symmetries that give rise to anisotropic alternating spin splitting in both momentum and real space. This distinctive property enables the observation of phenomena such as the anomalous Hall effect, previously believed to be absent in this class of materials.
