| 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 subjected to annealing at various temperatures from 923 to 1023 K for 5 min and then cooled in ice water. 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. |
