Effects of the thickness and deposition rate of Ta seed layer on the anisotropic mag-netoresistance and coercivity of Ta/Ni₆₅Co₃₅ bilayers

The effects of the thickness and deposition rate of Ta seed layer on the anisotropic magnetoresistance (AMP.) and coercivity ofTa/Ni₆₅Co₃₅ bilayers were investigated. The results showed that △ρ/ρ of Ta/Ni₆₅Co₃₅ bilayers could be improved at a certain thickness or higher deposition rate. The coercivity of Ta/Ni₆₅Co₃₅ films increased with the use of Ta seed layer. But the effect of the deposition rate on the coercivity of Ta/Ni₆₅Co₃₅ films was not significant.
