A series of Au/[Ni Co/Bi]x/Au(x = 2, 3) films were fabricated by pulsed laser deposition method. In order to induce the in-plane uniaxial magnetic anisotropy(IPUMA) of the multifilms, multiple layers and different oblique angles ranging from 0° to 30° for the substrate are applied during the deposition. The microstructures of the nanofilms were investigated by using X-ray diffraction(XRD) and transmission electronic microscope(TEM).And their magnetic properties were measured by an alternating gradient magnetometer. For the multicycle systems,using the method that with more periodic structures of Ni Co/Bi film is easier for inducing IPUMA than the less or the samples located with various angles.
