Magnetic Properties of PLD-made Nd-Fe-B Film Magnets and their Applications to Milli-size Motors
Abstract
We succeeded to deposite 200-300 μm thick Nd-Fe-B film magnets with (BH)max of approximately 55 kJ/m3 on Fe substrates by using PLD method. In addition, we confirmed that a milli-size motor, which was prepared from the obtained film, rotates at 15160 r/min under a no-load test.
