Abstract:
1. A magnetoresistive element comprising: a stabilization layer; a nonmagnetic layer; a spin-polarization layer provided between the stabilization layer and the nonmagnetic layer, the spin-polarization layer having magnetic anisotropy in a perpendicular direction and comprising a ferromagnetic material; and a magnetic layer provided on a side of the nonmagnetic layer opposite to a side on which the spin-polarization layer is provided, wherein the stabilization layer has a lattice constant smaller than that of the spin-polarization layer in an in-plane direction, and the spin-polarization layer contains at least one element selected from a group consisting of cobalt (Co) and iron (Fe), has a body-centered tetragonal (BCT) structure, and has a lattice constant ratio c/a of 1.10 (inclusive) to 1.35 (inclusive) when the perpendicular direction is a c-axis and the in-plane direction is an a-axis.
