Magnetic transducer and thin film magnetic head
An object of the invention is to provide a magnetic transducer and a thin film magnetic head having resistance properties adaptable to ultra-high-density recording. An MR element, the magnetic transducer, has a stack including a plurality of magnetic layers stacked alternately with a plurality of nonmagnetic layers. The stack has a first region and a second region into which the stack is divided in the direction of stacking thereof. The first and second regions of the stack differ from each other in the material or composition of the magnetic layers. The MR element has the above-described structure, thereby being capable of obtaining high resistance and a high rate of resistance change.
