CPP reader with phase detection of magnetic resonance for read-back |
摘要 |
An apparatus includes a magnetically biased multilayer structure having a reference layer and a free layer separated by a spacer layer; a DC current source connected to the multilayer structure; an AC current source connected to the multilayer structure; and a phase detector for measuring a phase difference between an AC current and a voltage across the multilayer structure. A method performed by the apparatus is also provided.
