Altermagnets are characterized by spin configurations that remain invariant under a combination of two symmetry operations: time reversal, which flips the spins, and a lattice rotation, which can be proper or improper. While altermagnetism is often considered in systems with negligible spin-orbit coupling (SOC), in this talk I will discuss interesting topological effects in altermagnets that are enabled by SOC. These include mirror-protected nodal lines and nodal points in the electronic spectrum, which have a significant impact on the properties of an altermagnet.
