摘要: Abstract In this paper, research works on Ba-ferrite (BaM) thin films achieved during the last two decades have been introduced. Magnetic properties of BaM/AlN were studied. Grain size BaM layer with an AlN underlayer was suppressed to 50–80 nm. A non-magnetic formed between and layers due diffusion Al. The H C⊥ for c -axis orientation 4.9 kOe at T S about 600°C.
