  • Magnetoresistive sensor with mixed phase antiferromagnetic film
    Patent number: 4782413
    Abstract: An improved thin film magnetoresistive (MR) sensor uses an iron-manganese (FeMn) alloy, with the alpha (body-centered-cubic) phase of FeMn present in the alloy, as an antiferromagnetic layer. The presence of alpha FeMn improves the longitudinal exchange bias in the ferromagnetic MR layer, especially when the amount of alpha FeMn exceeds the amount of gamma (face-centered-cubic) FeMn in the FeMn layer.
