A magneto-resistive element employs a CPP structure and includes an
antiferromagnetic layer, a pinned magnetization layer, a nonmagnetic
intermediate layer and a free magnetization layer that are successively
stacked. The pinned magnetization layer includes a first pinned
magnetization layer, a nonmagnetic coupling layer and a second pinned
magnetization layer that are successively stacked on the
antiferromagnetic layer, and the first and second pinned magnetization
layers are antiferromagnetically exchange-coupled. One of the first and
second pinned magnetization layer is formed by a ferromagnetic layer made
of a ferromagnetic material at least including one element or alloy
selected from a group consisting of Co, Fe, Ni and alloys thereof, and
the other is formed by a resistance control layer made of a conductive
ferromagnetic oxide.
