Abstract: While the understanding of altermagnetism is still in a very early stage,it is expected to play a role in various fields of condensed matterresearch, for example spintronics, caloritronics and superconductivity[1]. Concerning the field of optical magnetism, it is intriguing to studywhether altermagnets can host magnetization dynamic effects withdifferent properties from ferromagnets and antiferromagnets. Here wechoose RuO2, a prototype metallic altermagnet with a giant spinsplitting, and CoF2, an experimentally well studied insulatingaltermagnet, and calculate the inverse Faraday effect (IFE), i.e., laserinducedspin and orbital magnetizations, from first-principles.
