Patent ID: 7821748

Claim:
A magneto-resistance effect element, comprising: a fixed magnetization layer of which magnetization direction is substantially fixed to a single direction; a free magnetization layer of which magnetization direction changes depending on an external magnetic field; a spacer layer located between the fixed magnetization layer and the free magnetization layer, and having an insulating layer and an electric conductor passing current therethrough in a layer direction of the insulating layer; and a damping-factor adjustment layer disposed in at least one of the fixed magnetization layer and the free magnetization layer, containing one element selected from the group consisting of Ti, Zr, Nb, Mo, Rh, Pd, Ag, La, Hf, Ta, W, Re, Os, Ir, Pt, and Au, and having a thickness of 0.1 nm or more and 1 nm or less, wherein magnetization directions of upper and lower sub-layers of the at least one of the fixed magnetization layer and the free magnetization layer are parallel with each other, the upper and the lower sub-layers being separated by the damping-factor adjustment layer.
