Magnetic actuation has emerged as a powerful and versatile mechanism for diverse applications, ranging from soft robotics, biomedical devices to functional metamaterials.

Magnetic properties of hard magnets are currently attracting a great deal attention. In the paper, modified Harrison model was used to describe saturating hysteresis loops three praseodymium–dysprosium ribbons that differed in their chemical composition and processing conditions. Microstructural studies (TEM diffraction patterns) were performed for under consideration. The incorporates number p...
