AbstractWe have experimentally measured magnetostriction of thin CoFe layers when deposited with various seed and capping layers. Seed and capping layers were chosen to be materials that may be used in spin-valve (SV) type structures. Materials deposited adjacent to the magnetic layer include Cu, Ta and TaN. The experimental results are interpreted using a model that allows separation of bulk and interface contributions to the measured magnetostriction [1].Results show a clear interfacial contribution that is dependent upon the material at the interface of the magnetic layer. The results demonstrate that surface contributions to the magnetostriction dominate as layer thickness decreases.

Good Agreement

Based on the previous semi-classical model, we have performed calculation of the giant magnetoresistance (GMR) as a function of the thickness of the top/bottom or center ferromagnetic layers and the non-magnetic layer in dual spin valves. Our results are in good agreement with that reported in experiment, i.e., a GMR maximum is observed when the thickness of the top/bottom magnetic layer is at 20 ~ 40 Å; the GMR value decreases monotonically with the increase of the non-magnetic layer thickness. By considering the "pin-hole" effect, the variation of GMR versus the thickness of the center magnetic layer is also found to be consistent with the experimental result. These calculations will be helpful in the design of high-quality spin-valve structures.
