Ferromagnets have long been the foundation of spintronics applications, yet materials with compensated magnetic order, such as antiferromagnets, offer distinct advantages, including faster dynamics and a wider range of available materials. Altermagnets [1] are emerging as a class of materials that combine the advantages of ferromagnets and antiferromagnets, offering promising potential for spintronics applications [2]. Since their theoretical prediction, various experimental observations have already been reported [3]. In this talk, I will very briefly introduce spintronics with compensated magnets and the concept of altermagnetism and focus on some of the first experimental verifications of altermagnetic materials. I will present our magneto-transport studies in altermagnetic metals and semiconductors [4–6], and in the final part of the talk, I will discuss magnon-mediated spin transport in an altermagnetic insulator [7].
