摘要

•Al-doped BaM ferrite films were realized by post-annealing at a high temperature.•A BaM film with a large PMA field (HA = 18.1 kOe) and high remanence ratio (86%) was obtained by annealing at 1100 °C.•The obtained Al-doped BaM films show a potential application in self-biased microwave devices.
