ferromagnetic layers are antiparallel (Figure 7.1a), while in the latter case,
they become parallel (Figure 7.1b). Here, the current ows parallel to the
planes of the layers. Figure 7.1c and d represents the situation for current
owing perpendicular to the planes of layers.
The change in the resistance of the multilayer arises when the applied eld
aligns the magnetic moments of the successive ferromagnetic layers, as is
illustrated schematically in Figure 7.2. When the eld is absent, the magnetic
moments (the torque exerted on a magnet within a magnetic eld) are anti-
parallel (Figure ...
