Notes:
M-type barium ferrite (BaFe12O19) films were deposited on a ZnO underlayer by sputtering with mixture of Ar, Xe, and O2 gases. PO2 and PAr+Xe were set at 0.01 and 0.09 Pa, respectively, where PXe was changed from 0.00 to 0.09 Pa. The dependencies of surface morphology, 〈D〉, Δθ50, Ms, and Hc⊥ and Hc(parallel) on PXe were investigated. Both BaM layers deposited at PXe and PAr of 0.09 Pa possessed smooth surface and exhibited Δθ50, Ms, Hc⊥, and Hc(parallel) of about 4°, 300 emu/cm3, 2.0 and 0.3 kOe, respectively. The BaM layer deposited at PXe of 0.04 Pa possessed a rough surface and exhibited Δθ50 and Hc(parallel) as large as about 9° and 0.6 kOe, respectively, and Ms as small as about 200 emu/cm3.
