Abstract :
The magneto-optical properties and penetration depth of Ta/Cu/NiFe/CoFe/Cu/CoFe/NiFe/FeMn/Cu spin valve are studied. The samples are deposited on Si (100) substrate at room temperature by reactive RF magnetron sputtering technique. The electrical properties and penetration depth of the spin valve, the volume magnetic characteristic, and the near-surface hysteresis loops of the samples are measured using transverse Kerr effect spectrometer, vibrating sample magnetometer (VSM), and surface magneto-optical Kerr effect, respectively.
