INTERNALLY BIASED MAGNETORESISTIVE MAGNETIC TRANSDUCER

INTERNALLY BIASED MAGNETORESISTIVE MAGNETIC TRANSDUCER

A magnetic transducer exhibiting the magnetoresistive (MR) effect includes at least two thin film layers. An MR film in electrical control with a higher resistivity layer is magnetically biased by a portion of the MR sense current shunted through the nonmagnetic layer.
