<p>The present invention relates to a method for manufacturing a permanent magnet by using sputtering powder and, more specifically, to an advanced method for manufacturing a permanent magnet. According to the present invention, a high efficient permanent magnet with an enhanced magnetic force is manufactured by sputtering Dy and Tb on an Nd-Fe-B sintering magnetic powder to sinter them, which minimizes the amount of the Dy and the Tb used and with a simple and economical process, thereby making the high output magnet applicable for a driving motor.</p> |
