Abstract

A series of Au/[NiCo/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 NiCo/Bi film is easier for inducing IPUMA than the less or the samples located with various angles.
