Abstract

Spin valve structure as NiO/Co/Cu/Co/NiFe on glass substrate was prepared by rf magnetron sputtering. We systematically studied the effects of the deposit conditions such as biased pressure. sputtering power. gas pressure. deposit magnetic field and temperature of substrate on magnetic and magnetoresistance properties of this system. The influence of thickness of space layer Cu and inserted thinner Co layer in free ferromagnetic layer on MR is also discussed
