| Research Abstract |
In order to upgrade the torque of the small motor further, increase in the remenence value of the isotropic films is indispensable. In this study, therefore, we prepared nano-composite Nd-Fe-B/Alpha-Fe thick-films with dispersion structure by using a PLD (Pulsed Laser Deposition) method. In particular, we focused on the reduction in size and/or numbers of droplets by controlling the focus of laser beam. Resultantly, we succeeded in obtaining a Nd-Fe-B nano-composite thick film magnet with remanence, coercivity and (BH)max values of approximately 1.0 T, 400 kA/m and 100 kJ/m3, respectively.
