| dc.description.abstract | The effect of Fe, Cu, Zr, and Ti substitution on
magnetic properties of SmCo 1 : 7 magnets at temperatures up to
500 C were studied. As-milled amorphous Sm(Co,Fe,Cu,Ti???Zr)7
magnets crystallized in the TbCu7-type structure after annealing
at 750 C for 2 h. A room-temperature intrinsic coercivity of
around 2.5 T is obtained for compositions SmCo6 4Zr0 2Ti0 4 and
SmCo6 4Fe0 1Zr0 1Ti0 4. The high coercivity of the ball-milled
SmCo7 Ti magnets is attributed to the strong pinning of
the walls of the ???interaction domains?? by the network of grain
boundaries between the nanocrystalline grains. The virgin curve
of the ball-milled samples is suggestive of strong domain wall
pinning. | en |
