Magnetic detecting element having &bgr;-values selected for free magnetic layer and pinned magnetic layer
The present invention provides a spin valve magnetic detecting element having large &Dgr;R. The positive or negative sign of the &bgr; value of a magnetic material constituting each of a first free magnetic sub-layer, a second free magnetic sub-layer and a pinned magnetic layer is defined so that the resistance values for spin-up conduction electrons are smaller than the resistance values for spin-down conduction electrons in all magnetic layers when magnetization of a free magnetic layer is changed to minimize the resistance value. In this case, the change &Dgr;R in resistance of the magnetic detecting element can be increased.
