The study and application of conventional ferromagnets from antiquity to modernity has brought us some of the greatest and most wide ranging advances in technology. From the ancient compass to the modern hard disk drive, or even simple refrigerator magnets and the hundreds of complex sensors present in modern cars, countless inventions have resulted from the study of these materials. Research on the properties and applications of conventional ferromagnet systems continues to this day, reaching new advances every year. However, there are other unconventional types of magnetic systems that were previously considered uninteresting that we are now coming to learn have their own unique and interesting properties and potential. One such development in these unconventional magnetic systems is the possibility of stabilizing magnetic skyrmions at ambient conditions. These chiral spin textures, due to their nanoscale size and low current density driving mechanism, present the potential of a novel information carrier in next-generation nanodevices including ultra-dense, low power memory, and logic devices. In this talk, I will discuss the simulation and fabrication of these magnetic skyrmions in multilayer thin film systems.
