Study on the Characteristic of Spin Valve Film and Its Free Layer

Magnetic sensors based on spin valve structure become more and more important in the sensor family because of their good performance. During the research and development of magnetic sensors based on spin valve structure, the most important step is the preparation and optimization of spin valve film. Spin valve magnetic sensors with high performance are based on the spin valve film with high performance. This paper will introduce the characteristic and parameters of spin valve film and introduce the dependency of spin valve on free layer. This paper also introduce the optimization of free layer, which improves the performance of spin valve film.
