What is Investigation of Magnetic Hysteresis Properties of (Sm0.8Zr0.2)(Fe0.72Co0.24Ti0.04)10–12 Melt-Spun Ribbons about?

The structure and magnetic hysteresis properties of nanocrystallized melt-spun ribbons with composition (Sm 0.8 Zr 0.2 )(Fe 0.72 Co 0.24 Ti 0.04 ) z ( z = 10 -12) are studied. It is shown that substitution of a part of iron in the composition of the alloy by cobalt raises substantially the Curie temperature but almost halves the coercivity. The decrease is connected with growth in the volume fraction of the a-(Fe, Co) soft magnetic phase and incompleteness of the process of ordering of the ThMn 12 -type phase during annealing at 875 -900°C. In contrast to the rapidly hardened alloys not containing Co, hydrogenation of the of (Sm 0.8 Zr 0.2 )(Fe 0.72 Co 0.24 Ti 0.04 ) RHA powders is not accompanied by absorption of hydrogen and growth of the magnetic hysteresis properties.
