The article contains studies of micro- and domain structures obtained using atomic/magnetic force microscopy (AFM/MFM) of melt-spun Sm12.5Fe8Co65.5Zr1Cu13 thin ribbons in the as-cast state. In order to obtain the SmCo8.5 type of structure in the Sm–Fe–Co–Zr–Cu alloy, thin ribbons were manufactured using the melt-spinning method with large linear velocity of a copper wheel and proper selection of alloying elements. The obtained samples in the as-cast state were magnetized. The microscopic results were also supported by magnetic measurements performed on a vibrating sample magnetometer as well as by a quantitative analysis of phase composition obtained using the Rietveld refinement method.
