Altermagnetism (AM) refers to the recently unveiled collinear compensated magnetic order, capable of hosting spin-polarized electronic bands and facilitating spin-polarized currents. This emerging class complements the well-established categories of collinear magnets, namely ferro- and ferrimagnets (FM), and antiferromagnets (AFM), while it is delimited from the former through the application of spin space symmetries. Given that AM not only combines the advantages of both FM and AFM materials but also open new possibilities, the prediction of their theoretical framework and subsequent experimental validation has captured the interest of the research community. The objective of this conference is to establish a comprehensive platform for the discourse of recent advancements in AM and its intersections with various areas of condensed matter physics. This encompasses their fundamental properties, band structure, optics, material candidates and their compatibility with superconductivity.
