Abstract: The effect of boron substitution (x = 0, 0.005, 0.010, 0.015) on the structural and magnetic properties of Sm(Co(sub 0.86-x)Fe0.1Zr0.04B(sub x))7.5 and Sm(Co(sub 0.74-x)Fe0.1Cu0.12Zr0.04B(sub x))7.5 melt-spun samples is examined. Coercivity of 16.3 kOe was obtained for copper containing samples in as-spun ribbons with x = 0.015 while coercivity of 12 kOe was obtained in samples without copper after short annealing.
