发明名称 High SNR CPP reader using high frequency standing wave interference detection
摘要 An apparatus includes a current perpendicular to the plane sensing element, a DC current source connected to the sensing element, a microwave AC current source connected to supply AC current to the sensing element, and a detector for measuring a voltage representative of phase difference between the AC current and AC voltage across the multilayer structure when the sensing element is subjected to a magnetic field. A method for sensing a magnetic field is also provided.
