Özet

The structural and magnetic properties of ball-milled Fe-doped YCo5-xFex(0 <= x <= 0.5) were investigated. The magnetization increases with Fe-doping up to the solid solubility limit, x = 0.3 without destroying the crystal structure or degrading the coercivity. A special magnet array is designed using ring magnets for pressing the powders under magnetic field in order to achieve magnetic alignment. A dramatic increase in magnetization is observed for magnetically aligned YCo4.8Fe0.2 pressed ingots. (C) 2016 Author(s).
