“…For this study we have chosen a number of soft magnetic materials to be used as precursor for preparing SPS nanocomposite magnets: (1 (Ohnaka, 1985;Vazquez & Chen, 1995;Chiriac et al, 1998); (2 (Hilzinger & Kunz, 1980;Makino et al, 1990;Chiriac et al, 1997); (3) Fe 73.5 Nb 3 CuSi 13.5 B 9 (FINEMET) nanocrystalline melt-spun ribbons (4πM s ~ 12.4 kG) (Yoshizawa et al, 1988); (4) Fe 2 Co crystalline melt-spun ribbons (4πM s ~ 22 kG); and (5) commercial Fe micropowders (4πM s ~ 20 kG) of about 10 μm. The studies done up to know on Nd-Fe-B nanocomposite bulk magnets (sintered or bonded) used either Fe (Wei et al, 1994;McCormick et al, 1998;Lewis et al, 2001;Rada et al, 2005;Niu et al, 2007;Bhame et al, 2010;Cha et al, 2010) or Fe 2 Co micro or nanopowders (Wei et al, 1994) to increase the remanence and saturation magnetization of the respective PMs, whereas Fe, FeCo and Fe-B have been used in combination with Nd-Fe-B to prepare multilayered structures by deposition methods (Shindo et al, 1996;Cui & O'Shea, 2004;Ao et al, 2005;Kato et al, 2005).…”
