Magnetic properties of pulsed laser deposition-fabricated isotropic Pr-Fe-B thick-films magnets for magnetic micro-machines
抄録
A preparation of Pr-Fe-B thick-film magnets by using a PLD (Pulsed Laser Deposition) method with the energy density at approximately 50 mJ/m2 using the laser power of 2 W was effective to obtain the required magnetic properties for the application to a multi-polarly magnetized rotor. The isotropic films mainly consisted of Pr2Fe14B magnetic phase whose saturation magnetization is approximately 1.56 T, however the remanence (Br) showed higher than 0.9 T. The obtained value of B r was considered to be attributed to a remanence enhancement due to the interaction of Pr2Fe14B hard magnetic phases. Resultantly, the coercivity and (BH)max of the samples exceeded 600 kA/m and 115 kJ/m3, respectively, which were larger than that of previously reported PLD-fabricated isotropic rare-earth based thick-films.
