Abstract

An analysis of the precise chemical composition and spatial distribution of chemical components in thin DyPrCoFeB conductors was conducted. The magnetic stray field near the polished end of the microwire was studied, and the features of its surface structure were determined. The microhardness (9,56 GPa) and modulus of elasticity (159 GPa) of polished DyPrCoFeB samples were measured. The maximum allowable load limit (~6 N) was determined; exceeding this limit causes irreversible plastic deformation of the microwires.
