In one of the recent studies of the Laboratory of ferromagnetism, the scientific team from the Faculty of Science of the UPJŠ in Košice was able to explain the magnetization process in unconventional topologies of grain-oriented electrical steels with a rotating distribution of easy axes of magnetization [1]. Despite the high complexity of the problem, the research team succeeded in characterizing and elucidating the physical origin of the enhancement of the magnetic properties in these structures in specific spatial orientations. The goal of these results is to design more energy-efficient magnetic components in high-performance electric motors, thereby contributing to the sustainable development of new technologies.
