Abstract:
A mixed anisotropy magnetic field sensor includes a first magnetic material film having in-plane anisotropy with a first magnetic easy axis that is in-plane, a second magnetic material film having out-of-plane anisotropy with a second magnetic easy axis that is perpendicular to the first magnetic easy axis of the first magnetic material film, and a non-magnetic spacer between the first magnetic material film and the second magnetic material film. The first magnetic material film has a magnetization oriented in a first magnetization orientation parallel to the first magnetic easy axis in the presence of no applied magnetic field, and the second magnetic material film has a magnetization oriented in a second magnetization orientation parallel to the second magnetic easy axis in the presence of no applied magnetic field.
