A laminate structure includes an antiferromagnetic layer, a pinned magnetic layer,
and a seed layer contacting the antiferromagnetic layer on a side opposite to pinned
magnetic layer. The seed layer is constituted mainly by face-centered cubic crystals
with (111) planes preferentially oriented. The seed layer is preferably non-magnetic.
Layers including the antiferromagnetic layer, a free magnetic layer, and layers
therebetween, have (111) planes preferentially oriented.
