We offer a brief overview of the present status of ultrafast helicity-independent all-optical magnetization switching (HI-AOS) phenomena in ferromagnet (FM) films and multilayers. The discovery of HI-AOS in ferrimagnet alloys dates back to 2011. From an application standpoint, utilizing HI-AOS in an...
