Abstract
Flicker noise comparison has been made on single layer NiFeCo, Sandwic h AMR NiFeCo/TaN/NiFeCo and GMR NiFeCo/CoFe/Cu/CoFe/NiFeCo films. In a single magnetic domain state, AMR films have noise close to the therm al noise, GMR has 2-3 times higher noise, and in a state having a usef ul MR ratio, the GMR film has 10 times higher noise than AMR sandwich film, while the sandwich film has 10 times higher noise than single la yer AMR film.
