Abstract

Spin valve systems based on the giant magnetoresistive (GMR) effect as used for example in hard disks and automotive applications consist of several functional metallic thin film layers. We have identified by secondary ion mass spectrometry (SIMS) two main degradation mechanisms: One is related to oxygen diffusion through a protective cap layer, and the other one is interdiffusion directly at the functional layers of the GMR stack. By choosing a suitable material as cap layer (TaN), the oxidation effect can be suppressed., Comment: 3 pages, 3 figures. to be published in Appl. Phys. Lett

Abstract

X-ray magnetic circular dichroism (X-MCD) combined with anomalous small angle x-ray scattering (ASAXS) enables size distributions and correlations lengths in the nanometer range of magnetic precipitates in granular systems to be determined. Standard ASAXS measurements on an amorphous GdFe system, taken at the Fe K edge, gives information about the electronic structure. Magnetic scattering curves were obtained at the corresponding Gd L(sub3,2) edges.
