A free magnetic layer contains free magnetic material layers and an
intermediate layer interposed therebetween. A fixed magnetic layer
contains fixed magnetic material layers and a non-magnetic intermediate
layer interposed therebetween. The free magnetic material layer and the
fixed magnetic material layers are formed at equivalent film positions.
The magnetizations of the fixed magnetic material layers provided in a
vertical direction are antiparallel to each other, and the magnetizations
of the free magnetic material layers provided in the vertical direction
are antiparallel to each other. By an external magnetic field, the
magnetizations of the free magnetic material layer are rotated in phase
to magnetization directions of the fixed magnetic material layers.
