Magnetoresistive effect and anisotropy field of Ni-Co films deposited under orthogonal switching field were studied. The magnetoresistive effect was maximum for 77 Ni-Co films. The anisotrophy fields were 0.4-0.7 kA/m for these films. Demagetization field, domain structure and magnetization process were investigated for the composite Ni-Co/ Ni-Fe film of a striped configuration. When had thick Ni-Fe films are placed near the Ni-Co films, the demagnetization field were small, domain walls were short and magnetization processes were homogeneous.
