N2 - An advanced preparation method was carried out to obtain a magnetized cylindrical micro rotorfabricated from directly consolidated isotropic -Fe/Pr2Fe14B nanocomposite thick-films with self-bonding layer. A magnetic torque of the above film with the remanence value of 0.97 T, the coercivity value of 650 kA/m, and the (BH)max value of 142 kJ/m3 was investigated under different field strengths. Namely, magnetic torque of the above-mentioned rotor with a single pole pairincreased by 117, compared with that of Fe3B/Nd2Fe14B films with the remanence value of 1.1 T, the coercivity value of 334 kA/m, and the (BH)max value of 95 kJ/m3. It was found that the use of -Fe/Pr2Fe14B films is effective in obtaining a multipolarly magnetized micro rotor with highly dense torque as well as magnetic stability.
