ABSTRACT:
A magnetoelectric transducer is proposed using the GMR effect which operates stably even in a wider range of magnetic field, and over a wider temperature range, than currently available. Upon a substrate 5 there are formed a first magnetic layer 1, a non magnetic layer 3, a second magnetic layer 2, and a rare earth--transition metal alloy layer 4. The second magnetic layer 2 and the rare earth--transition metal alloy layer undergo exchange coupling. The axes of easy magnetization of the second magnetic layer 2 and the rare earth--transition metal alloy layer 4 lie along the surfaces of these layers. The composition of the rare earth--transition metal alloy layer 4 exhibits rare earth dominance at room temperature. The main component of the non magnetic layer 3 is Cu, and the thickness of this layer 3 is at least 1.5 nm.
