The aim of this paper was to study the phase constitution, magnetic properties, and magnetization reversal processes in the Pr8Dy1Fe60Co7Mn3Ni3B14Zr1Ti3 alloy ribbons. The ingot samples were obtained by arc-melting of high purity constituent elements. The single roll spinning technique was used for producing rapidly solidified ribbons. Melt-spun ribbons were produced from the base alloy at the different surface velocity of the copper wheel. Subsequently, the fully amorphous ribbons were

The X-ray diffraction was used to determine phase constitution of all obtained samples. Nanocomposite structure of produced ribbons was obtained during short-time annealing. The magnetic parameters were determined from magnetic hysteresis loops measured in the external magnetic field up to 2 T at room temperature. In order to clarify the occurrence of possible interactions, the Henkel plots were constructed. topics: hard magnetic materials, melt-spun ribbons, magnetic properties, Henkel plots
