| heal.abstract | In this work we examine the effect of small boron substitution (x=0, 0.005, 0.010, 0.015) on the structural and magnetic properties of Sm(Co0.86-xFe0.1Zr0.04Bx)(7.5) and Sm(Co0.74-xFe0.1Cu0.12Zr0.04Bx)(7.5) melt-spun samples, as a function of wheel speed and annealing conditions. Boron substituted as-spun ribbons are found to have increased coercivity, Hc>5 kOe, and small grain size of 60-100 nm. For copper containing samples, the highest coercivity (Hc=16.3 kOe) was obtained in as-spun ribbons with x=0.015. In samples without copper the coercivity increased after short annealing (Hc=12 kOe for x=0.015). The large coercivities are attributed to a fine microstructure consisting mainly of hexagonal TbCu7-type phase and a small amount of soft-phase grains. (C) 2002 American Institute of Physics. | en |
