The magnetic behaviour of sputtered Py5nm/Cut/Co5nm films on glass, Si(100), and Si(111) was studied by measurements of the transverse, longitudinal, polar magneto-resistance, and the magneto-optical Kerr effect (MOKE). The sample can be rotated about its surface normal to obtain angular dependent information during the MOKE measurement. All specimens have non-vanishing normal component of magnetization as revealed by MR with field applied normal to the film and confirmed by polar MOKE. Spin valve MR with very small coercivity is observed as t is increased. The minor R-H curve shows two states at zero magnetic field, which is desirable for MRAM application. An increase in the periodicity number increases the MR ratio, but also, significantly, the coercivity.
